GP3/GP2K don't run on W7 i think, and definitely not 64bit.
GP4 you have to make sure you run it in administrator and compatibility mode for windows XP before installing the patch (9.6) or gpxpatch (run it before both). Updating is simple, use CSM to install carsets, should work fine
If you need more detail let me know!
