Earlier today I released a new copy of our Windows 101 course that was compiled to work with Vista. I've gotten some positive feedback from a bunch of customers saying it's working.
Now I just have to finish recompiling all of the other courses so those of you with Vista can download them. Sorry for the wait.
Microsoft didn't do too good of a job making sure Vista was completely backward compatible with all of their OWN software (like Windows Media Player).
If you'd like to try the Windows 101 course yourself to see if it works with your Vista system, you can download a free copy of it. I posted it on our WHATS NEW page.
