To the best of my knowledge, all office subscriptions include both 32 bit and 64 bit versions. Its annoying that even by today's standards, the 32 bit is still the default download when getting it from the microsoft site.

My recommendation, if possible, is to get your end user to log into their office 365 and download the 64 bit version of office and upgrade - it doesn't cost anything and future proofs (When going to the download, they'll need to select advanced options, rather than downloading the default)

I'm upfront about not supporting 32 bit. Its an unnecessary pain when nearly all computers these can run 64 bit applications. Furthermore, you'll be removing the 32 bit performance limitations which could seriously affect your access processing.

^^ Dan I don't think that is the case any longer.  I recently had to go looking for 32bit as I didn't want to have one machine different on a new computer.
I still haven't made the switch.  Don't want to deal with it right now.

Change is coming! Wonder when 128bit comes out?

Dan probably the same time as Access.NET. LOL

Yeah, I'd say keep ALL of your installations on the SAME bitness. If one person is 32-bit, you should ALL be 32-bit. But, try to get everyone up to 64-bit if you can. Working between different versions is a nightmare.
