Win7 tries to manage a number of user file types like game saves, docs and others. It wants to automatically put them in a user's app data location and in some cases will even though the ap doesn't expect that. Older and even some newer programs that default to the programs(x86) install location expect to find their files where the application wants to put them and can't when win7 shortstops 'em and puts them where it thinks they should be. to keep win7 from doing this apps designed under XP or earlier should be placed in their own directory outside of the programs(X86) folder. One would think that setting compatibility would fix the issue. Usually does in my experience but not always. I have at least one app, POA2 that putting it in the default programs folder on install may or may not run right. some of the Tiller games won't run if installed into the default programs folder in win 7 some experience no problems others have to do an install outside of the default. check the MS knowledge base - its in there somewhere. I think that most of the issue is with folks who turn off UAC in win7. But that is just my opinion, I can't prove it.
