I'm not a tech sort of person, Charllotte, so take this for what it's worth. I have Win 7 Pro 64 bit on my computer and I'm seriously considering removing the Virtual XP that I was so sure I needed. Win 7 Pro can play nearly every game I've tried on it, including Grim Fandango with the patch and installer I downloaded for it. Those that it can't play won't open or play in Virtual XP either. Now, that may be because it's 'virtual' and somehow different from the real thing, I don't know but if I had to do it again, I'd forget the virtual XP.
