Troubleshooter By Richard Rost 
Microsoft Access Database Troubleshooting Checklist I get emails all the time from people with Access issues. All of the problems and questions from many of you have inspired me to start this: the Access Debugging and Troubleshooting Checklist. I know I've pulled my hair out with strange Access problems that sometimes seemed to get fixed by the strangest things. I went nuts one day trying to fix a bug and it turned out I just needed to reboot the PC. Low system resources can cause any number of problems, including forms not opening, reports not printing right, crashes, etc. So, here's my list of troubleshooting tips when you've got that Access problem that just will NOT go away. I have tried to rank these in the order you should check. The least painful fixes (quick and easy) are first. Try each one in order. If that doesn't work, move on to the next one. Backup First My standard disclaimer applies. Before doing anything with your database, you should always make sure you have a good backup. 'Nuff said. Restart Access Close and restart your database. Restart All Access Databases Close and restart any and all Access databases. You may also want to check the Windows Task Manager and make sure that all instances of Access are closed. Kill MSACCESS.EXE if you have to. Compact & Repair From inside your database, go to Database Tools > Compact & Repair. See this video for more on the Importance of Compact & Repair. Compile the Database In the VB editor window, go to Debug > Compile [Database Name]. You'd be surprised what bad code in one Module will do to another. Usually this just highlights syntax errors, but you'd be surprised sometimes. See the Compile TechHelp video for complete instructions. Don't Use Online Storage Make sure you are not running your database from any folder that gets backed up or synched by offline "cloud" storage programs like OneDrive, DropBox, Google Drive Sync, etc. These programs can try to backup your database file while Access is using it, and cause records to get locked unexpectedly, or even the whole file to get corrupted. See this post for details: Access Online. Run on Local Drive If your database runs over a network, try copying it to a local hard drive. See if the problem persists there. Likewise, if your database is split into front/back ends, try bringing the tables back into your front-end and see if the problem goes away. Check For Known Bugs If you are experiencing a weird error with Microsoft Access you may have encountered a known bug. Check these sources to see if it's already been reported: Trusted Location If features in your database aren't working (like buttons when you click on them) make sure your database is run from a Trusted Location. Option Explicit If you are programming in VBA, make sure you have Option Explicit in your code. Problems With My Databases If this is a database you downloaded from my website, Does this behavior happen in the stock database you downloaded from my website? If you've made any changes to the database then the error could have crept in at any time. Test the original database right after downloading it and if this problem occurs it may be a bug and I'll be happy to fix it. But if you've made changes then I don't know what you've done and I won't be able to tell what the problem is without knowing what you've done. Restart Office Close and restart any open Microsoft Office Applications. They share DLLs so even a misbehaving Excel file can keep Access doing weird things. Reboot the PC That game you were playing last night might have eaten up your available memory. Those Recorsets that you DIM'd and forgot to set to Nothing at the end of your loop... yeah, you may have memory leakage or other low system resources. Give it a quick reboot. I know rebooting is a pain. Go get coffee. Make sure you do an actual Restart of Windows. Reboot Clean If you have any other applications that load with Windows (virus scanners, etc.) reboot without them. Run your Access database on a clean, fresh startup. Something else might be interfering with your database. Restart with the SHIFT KEY held down so it bypasses your Startup apps. Remove Debugging I know it sounds counter-intuitive, but if you can't figure out why your VBA code isn't working, remove any debugging statements like On Error Resume Next. They could be hiding an error that will explain why it's not working. Decompile the Database If compiling the database doesn't fix the problem decompile and recompile it. See the Compile video for instructions. Rename the Object This may sound like a really weird one, but I had this specific form giving me a runtime error 459 every time I opened it. Tried everything. Couldn't figure it out. On a whim, I renamed the form. Worked! So when a particular object is giving you a hard time, just try renaming it. Form, table, control, variable, whatever. Google It Try a quick Google search for your problem. You never know, someone else might have experienced this exact same issue before and has a fix for you. Try a Backup Sometimes the problem may be due to something you recently added to your database. SAVE your current database (set it aside, rename it) so you don't lose any data. Then try restoring your most recent backup. If that works, then the problem was caused by something you changed. If that still doesn't fix the problem, try your next oldest backup. That should help you nail down when the bug crept in to your database. Try Another PC Believe it or not, I had a database once that would not work on one specific computer. The client called me in several times and I couldn't figure the problem out. It worked fine on every other machine in the office, and no other application (Word, etc.) had issues. Just my database. Turns out it was a faulty keyboard. For some reason, there was a short that affected Access in some way. No idea why. Replaced the keyboard. Database ran fine. Weird? Yes. But that's technology for ya. Office Update Bugs happen. Microsoft is fixing bugs all the time. Sometimes an update creates a bug. The best way to make sure you don't have a problem with a known bug is to run an Office Update if something doesn't seem right. In any Office application, go to File > Account > Office Updates. Rollback Office Update If this problem seems to have appeared after an Office Update, you can rollback to a previous known good version. Sometimes new updates break things that previously worked. See this video for details: Rollback Windows Update If you're sure you have the latest version of Office installed, make sure Windows is up to date too. The two are closely related. Bugs in Windows can cause your database to act weird. It's happened to me. Run a Windows Update. From the Start Button just search for "Windows Update." Scan for Viruses If you share or download files, you could have a virus. In which case your system could exhibit any number of odd behaviors. Open "Windows Defender." Make sure your virus definitions are up to date and run a complete scan of your system. Check Database File Size If your database, or any attached back-end databases, are getting close to the 2 GB maximum size limit, this could cause any number of random problems. Remember, Access is constantly working with hidden index and system tables. If it can't create or modify any of these, for any reasons, you might get weird errors. Try to keep your database files under 1.2 GB if possible. If not, split them. If you have a single table over 1 GB, you should optimize it, dump old data, or upgrade to SQL Server. Create a New Object (Form, Report) Got a form or report that's misbehaving? Once you encounter a problem with a form, it could be stuck somewhere in the form's design. What I usually recommend is if you have a form and it's causing errors and you can't figure out why, just build a new form and then delete the old one. New Database File Just like forms and reports can get corrupted, sometimes ACCDB files get weirdly corrupted. Even after a C&R it might not be acting right. Create a blank new ACCDB file and import the misbehaving object(s) into it. If they work, the problem is a bad file. Proceed to import the rest of your objects until you find the culprit. Check Remaining Hard Drive Space Check to make sure you have plenty of free space available on your hard drive. You should have at least twice the space available as your database file size. So if you have a 1.5 GB database, you should have at LEAST 3 GB of free space available. If not, free up some space or upgrade your drive. Update Device Drivers Make sure all of the drivers for all of the devices on your PC are up-to-date. Believe it or not, I had one client whos database kept crashing every time he tried to preview a report because his printer drivers were bad. Updated them with the latest drivers and BAM! Problem solved. Remove 3rd Party Components Your problem might be with a 3rd party DLL, OCX, or other plugin. Remove 3rd Party Software Sometimes software that you have installed from other 3rd party vendors may replace DLL files that Microsoft Office needs to run properly. This is usually a problem with "independent" software authors, shareware, etc. Try removing any non-Microsoft software from the machine. You may need to reinstall Office after removing the offending program to put the proper DLL back. If you are going to go so far as reinstalling Windows (see below) then I would suggest install a fresh copy of Windows and then a fresh copy of Office (Access) before you install anything else. This will definitely determine if it's a 3rd party software conflict. Reinstall Office Sometimes files get corrupted and an Office Update won't repair them because it doesn't know to look for them. I've had bad DLL files before that have wrecked havoc on my system, and everything was up to date. Sometimes you need to completely uninstall Office first, so that everything is deleted, and then reinstall it. Don't just install over an old copy. If you have remnants of older versions of Office on your system, delete those too. Upgrade Office I'm not usually someone who pushes "the latest and greatest" upgrade on people. I've always been of a mindset "if it ain't broke, don't fix it." However, sometimes problems with older versions can go away in a newer one. Sometimes they fix things that you might not have known were broken. Reinstall Windows Sometimes you might have a corrupted Windows DLL file. You may need to try working from a fresh install of Windows. If you have tried everything else AND your database works fine on another computer, this may be your only option. Get Help If you've checked everything off on this list and you still need help with your database, let us know. We'll do our best to help you out. Your first line of support is the Access Forum. Post your problem there. I try to check them as much as I can, plus I've got a great team of Moderators that help out a lot (and I'm super appreciative of that!). I no longer offer one-on-one technical support or Consulting, however if it's business critical, you may be able to get assistance from one of my Moderators, students, or colleagues via the Access Developer Network. Specific Issues or Error Messages The above items are for generic "weird" problems that don't always have a specific problem you can pinpoint. The following are some common issues or error messages that may come up and solutions on how to fix them. I'll add to this list as time permits.

IntroIn this video, we will talk about troubleshooting common issues with Microsoft Access databases. I will walk you through my recommended checklist for diagnosing and fixing problems, including steps like making backups, running compact and repair, restarting Access and your computer, checking for software updates, running virus scans, and trying your database on another computer. I will also discuss advanced options such as importing objects into a new database, compiling code, and dealing with third-party plugins. This is a step-by-step guide to help you resolve those frustrating Access issues that can pop up unexpectedly.TranscriptWelcome to another TechHelp video brought to you by AccessLearningZone.com. I am your instructor, Richard Rost.In today's video, we are going to go over Troubleshooting Access. This is my checklist for troubleshooting your Access problems. Today's question does not come from one person; it comes from literally thousands of students from everywhere. The emails always start off like this: "I've got a problem at database. It's not working. It was working before. Can you help me?" First, I have to say, if you are looking for help with your Access database and you are emailing or chatting with an expert online, give as many details as you can. What is not working? Are you getting an error message? What have you tried? If you just say, "It's not working," that is not a lot for me to go on. Before I dig into your database and try to help you solve your problem, I am going to point you to my Access Troubleshooting checklist. This is on my website. There is the URL: 599c.com/trouble. Go here first and run down this list and check all of these things. This list is updated from time to time, so in addition to watching this video, where I will give you some extra tips, check the checklist and make sure that I have not added anything new to it. Like the checklist says, I pull my hair out with strange Access problems all the time too. Sometimes the weirdest things happen: your code does not work, your forms will not open, and you cannot figure out why. I went nuts one day trying to fix a bug and it turned out all I had to do was reboot the PC. It was the last thing that I tried, and I spent hours and hours trying to fix this problem. I rebooted the computer and everything worked. Sometimes weird problems creep into your databases and it is not the database's fault. It could be something crazy going on in Windows. Here is my list of stuff and this is what I recommend you do in order. I try to put these in order of "try these things first" because they are simple and easy, and then we will get into more complex things as we go along. First, of course, is back up your database before you do anything. You should have a nightly backup running. If not, get a backup system going first. Make sure you back up everything. The next thing to try: a compact and repair. The number one thing you should do whenever your database is not running properly is a compact and repair. It is inside your database; go to Database Tools, Compact and Repair. Very easy to do. It is right in here: Database Tools, Compact and Repair. Not only is this a good idea to do on a regular basis to get rid of any extra empty space in your database and to keep it nice and small and efficient, but the repair part of it can actually fix any problems that Access sees with the database structure itself, so that is always good to do first. Next up, restart Access. Believe it or not, just closing the database down and then restarting it could make your problem go away. If that does not work, restart all of your Access databases. I have had situations before where I have had multiple databases running on the same computer. One was the work database, another was a background email server, and so on. A problem with any one of those could cause problems with all of them. They use the same shared DLLs, the same resource files in the background, and if any one of them has memory problems or any kind of issues, it could affect all of the Access databases on your machine. The same goes for all of Microsoft Office. Excel and Word have a lot of shared files that all the Office programs use. If you restarted all your Access databases and you have Word and Excel running, restart all of your Office applications. The next logical step: you have restarted all of Office, you have shut down and restarted all of your Access databases. Reboot the computer. Back in the old days, this was really painful, having to reboot your computer. I remember when I started, rebooting your computer could take five minutes. You would go get coffee, come back, and it was still sitting there loading Windows. You may have some other misbehaving programs on your computer, a game that you played last night, for example, or something else that is just causing you memory leaks. You have no idea. Reboot the computer, give it a fresh start. Nowadays, my Windows 10 machine boots in like 15 seconds. It is nice and quick, it is nice and fast. Go get some coffee if you have to, but reboot the computer and give yourself a fresh start. If you have anything - I should probably add this to the list - I always come up with ideas: if you have any startup programs that are loading, I am going to add this to the checklist. There we go: reboot clean. If you have any startup programs in your Windows startup folder, try disabling those and then boot your computer. That may solve the problem. Next, try a backup. Sometimes the problem could be something that you recently did to your database, a change you made, some form you edited, some code you added. Save your current database, set it aside, rename it so you do not lose anything. You do not want to lose your work. Try restoring one of your more recent backups that you know worked. If that database worked, then the problem was caused by something you recently changed. That will help you go in and troubleshoot where the problem crept in. If that still does not fix the problem, try the next oldest backup. If you know something from two weeks ago worked, try restoring that backup. That should help you nail down at least where the bug crept into your database. Try a different computer. If you have got a different PC or a different laptop or something else you can try the database on, do that. The story here says, I once had a database that would not work on one specific computer. The client called me several times and could not figure out what the problem was. It worked fine on every other machine in the office and no other application like Word had issues. Just the database that I built. Turns out it was a faulty keyboard, believe it or not. For some reason, there was a short that affected Access in some particular way. It somehow manipulated just a certain region of the computer's memory. I have no idea why. I do not know what the problem was exactly. Replaced the keyboard and the database ran fine. It was weird. It is completely weird. I have no reason why a keyboard would affect my Access database and only my Access database. Everything else ran fine. It joined the network. Word and Excel ran okay. Just this database. Next, try an Office update. Bugs happen. Microsoft is constantly fixing bugs all the time. Sometimes an update creates a bug. Especially if you have got auto updates on, you can install an update and then a bug creeps in. Just recently, in fact, Microsoft did something in one of the updates that caused the Shift+F2 zoom not to work in Access. Worked for years. I did not cause any problems. I did not make any major changes. All of a sudden, I would hit Shift+F2 to zoom into a field in my Access database and the whole application crashed. It only happened on my Windows 8 machine and not my Windows 10 machine. That was even weirder. I Google searched it and Microsoft had posted that it was a known bug. They were working on a fix. They promised a fix in a couple of days. They posted an update and everything was fine after that update. So it was a known bug. Someone else discovered it. They knew about it. Do an Office update and make sure that you have the most recent version of Access and the most recent version of Office and everything should hopefully at that point go fine. If not, try updating Windows. Make sure you have the latest version of Office and Windows installed. Bugs in Windows, even if it is something like a networking bug, could cause Access not to run right, especially if you are using Access over a network. Run a scan for viruses. This might be something that you are doing regularly anyways, but if you have a virus or an old Trojan file or something on your computer, it could cause any number of problems. I am very careful. I do not download and run any software that I am not sure comes from a reputable site, but even then, you could sometimes get viruses. You never know. So do a virus check. I am not a big fan of buying third-party virus software. I think Windows Defender that comes with Windows is just fine, but make sure you update your definition files and you can do that in your control panel. Make sure that it is up to date. Do a scan. Make sure that you do not have any viruses on your computer. Especially, again, if you have tried this on other computers and it works fine, it is an issue on your machine. This one is a little more involved, but set up a new database file. Sometimes a specific database file, ACCDB file, can get corrupted even though the objects inside it are fine. I have seen this happen before, and a compact and repair might not fix it. Here is what you do. Create a new ACCDB file, a blank file. Move your objects into it from the other database. Do a file import; pull them in. Start a few objects at a time if you want to. You can try pulling them all in first and see if that fixes the problem. If not, pull them in one at a time. Pull in your customer table, your customer form, your main menu, all that stuff, and see if it works. It could be a corrupted ACCDB file. I have seen it happen before. I tell the user, import all the objects into a blank new file, and then it just mysteriously works. Why? No idea. Another thing to try. Next, especially if you have got a lot of code and a lot of modules in your database, compile the database. In the Visual Basic Editor window, go to Debug, Compile. You would be surprised what bad code in one module could do to another. This usually highlights any syntax errors you have, but sometimes you will be surprised at what it will point out. Inside your database, if you have a module down here (I do not have any in this database), you could open those up. If not, just go into any form. Go to the little button here that says View Code. That will bring up your VBA editor. Just go up to Debug and then Compile. Now mine is greyed out because I have not made any changes since the last time I compiled it, but I will just make one little change, just backspace over something here. Debug and then Compile. If nothing happens, your code is clean. If it finds errors anywhere in any module in your database, it will generate an error message for you and you will be able to fix it. Next up, you have gone through all these things. The next thing to try is reinstall Office. I know this is a pain. This takes a while to do, especially if you have got 365 and it will have to download again. But sometimes you could have a corrupt Office file. That is why it is important to completely uninstall Office first. Do not just install it over the copy that you have right now because Office will not necessarily copy all of the shared files back over again. Remove every trace of Office from your computer, including Word and Excel and PowerPoint, everything else. Do a complete Office uninstall, then reinstall it fresh again. That will make sure that you have got all those DLLs, all those shared files, back on your system. This is especially true if you have installed Office over older versions of Office. On the same machine, you had Office 97, then you upgraded to Office 2000, then you upgraded to Office 2007, then 2013, now you have 365. You have one machine that you have had for years with all these different versions of Office on it. The installs might not have cleaned up all the old garbage from the older versions. The next logical thing is reinstall Windows. I might add that to the list, but I would not say go that far for an Office problem. But again, that goes into "try your database on a fresh machine." If you have got a machine that is relatively new in your office with a brand new copy of Windows, a brand new copy of Office on it, try your database on that one and see if it works. Reinstalling Windows is the next logical step though. So there is reinstall Windows on there. You might have to, if you have tried everything else and your database works fine on another computer, especially if you have taken it over to Joe's accounting machine and his database works but yours does not, it could be a problem with Windows. Could have a corrupted DLL file from Windows. There are a lot of shared files in there that all your applications, including Office, use. I also added another one on there: remove third-party components. If you have got plugins that you have purchased or downloaded from some site on the web that you have plugged into your Access database to do other things like a tree view control, I have seen those cause problems too. That is why I try to stick with just things that are built into Access. If you have taken any of my lessons, you will know that I do whatever I can without relying on third-party plugins. There is some cool stuff out there too, but it does not always work. It does not always behave. It certainly is hard to distribute your database to other people if you have got these third-party plugins. If you have got something cool that works on your machine, it might not work for everyone else, especially if you are on a network and you have got a bunch of different people that want to be able to use this database. I try to stick to things that are just built into Access, but I have seen those third-party components cause problems, especially when it works on your machine and you distribute it and you are trying to troubleshoot that machine. Why is Joe's accounting machine not working now? It is because of that third-party plugin. You remove it and everything works fine. That is pretty much my entire checklist. If you have any thoughts, anything you want to add to this list, please let me know. If you have run down this entire checklist and you are still stuck, feel free to contact me. There are a couple of different ways you can contact me. There are links on the page. This line is the Access Forum.

Before I finish the video, I want to give a big shout out to my buddy Alex. He has been my right-hand man. He has helped with a lot of these issues coming up and adding stuff on the troubleshooting checklist that I completely forgot about. I am like, "Oh, yeah, why did I not think of that?" As soon as Alex throws something at me, I put it on the checklist. So again, Alex, thanks a lot for your help.

SummaryToday's video from Access Learning Zone focuses on troubleshooting Microsoft Access. I get questions from students all over the world, often with a similar message: something in their database suddenly stopped working and they are not sure why. My aim today is to provide a comprehensive checklist to help you systematically resolve issues with your Access database.When you are seeking help, always provide as much information as possible about your problem. Share what exactly is not working, any error messages you receive, and what you have already tried. The more details you give, the easier it is for someone to assist you. Before I offer any specific solutions, I want to highlight my Access Troubleshooting checklist, which you can find on my website. I update this list regularly, so it is a good idea to review it in addition to watching this video to catch any new tips that might be available. Strange problems can crop up in Access without any clear cause. Sometimes, your code or forms will stop working and you cannot immediately figure out the reason. I have spent hours chasing down bugs only to find that a simple computer reboot was the answer. Odd behavior can result from all sorts of things, often outside of Access itself, such as issues in Windows. Let me walk you through the steps I recommend for troubleshooting, in the order you should try them, starting with the simplest solutions. First and foremost, always back up your database before making any changes. Regular, automatic backups are essential. The next step is to perform a compact and repair. This is a standard maintenance procedure in Access. You can find this under Database Tools. It helps keep your database running efficiently and can fix certain types of structural problems. After that, try restarting Access. Simply closing and reopening the database may resolve some issues. If you have multiple Access databases open, close them all, as problems in one can sometimes cause trouble for others due to shared resources. If you are running other Office programs like Word or Excel, restart those as well. All Office applications share common files and resources, so a glitch in one program can affect others. If restarting the applications does not help, the next logical step is to reboot your computer. There could be other misbehaving programs or processes in Windows affecting Access. These days, rebooting is quick and painless but can solve many stubborn problems. If you have startup programs that automatically load when Windows starts, try disabling them and performing a clean reboot. Sometimes these background applications create conflicts. If the problem appeared after recent changes to your database, try restoring a backup from before the issue began. Make sure to save a copy of your current database so you do not lose recent work, and then restore previous versions to see if the issue goes away. This can help you pinpoint when the problem first appeared. Another useful step is to try running the database on a different computer. There have been cases where a database fails on one specific machine but works fine everywhere else. In one instance, a faulty keyboard caused repeated database failures, but replacing the keyboard resolved the issue. The point is that sometimes the problem is related to the hardware or environment, not the database itself. You should also check for and apply any available updates for Microsoft Office and Access. Microsoft regularly releases updates to fix bugs, and sometimes known issues are resolved in these updates. Occasionally an update can introduce bugs as well, so staying current and reviewing known issues can be helpful. Similarly, update Windows itself. Operating system bugs or networking issues can affect how Access behaves, especially when used on a network. Running a thorough virus scan is also a good idea. Malicious software or malware can interfere with many types of programs, Access included. Windows Defender is usually sufficient, but be sure your definitions are up to date. If the above steps do not solve the problem, try creating a new, blank Access database. Import all your objects from the old database into this new file. On rare occasions, the database file itself can become corrupted, even though the objects inside work fine. A fresh ACCDB file often resolves unexplained issues. For databases with complex code, go into the Visual Basic Editor and use the compile function. Syntax errors or conflicting code in one part of your project can cause issues elsewhere. Compiling will highlight any of these errors for you to fix. If you have tried all of these steps and the problem persists, reinstalling Office may be necessary. Fully uninstall Office first, ensuring all components are removed, and then reinstall it. Over time, multiple upgrades and installs can leave behind corrupted files or misconfigured components. In more extreme cases, consider reinstalling Windows, especially if the problem seems restricted to one machine and does not appear elsewhere. A clean operating system is sometimes the only way to clear up deeply embedded issues. Additionally, review any third-party plugins or components you may have added to Access. These can cause compatibility issues, especially when sharing the database with others or running it on different machines. I usually avoid relying on anything outside of what is built directly into Access. Removing problematic add-ons often resolves conflicts. That covers my main troubleshooting checklist. If you have suggestions for other steps to include, I encourage you to share them with me. If you have thoroughly worked through the list and still need assistance, you are welcome to contact me.
