Hi SW. I don't have Windows 7 yet but as I understand, just run SH5 on your 32 bit 7 install. Less problems. And don't jump on Windows 8. I was told at the MS store at our local Mall that it is not a gaming OS yet. MS is actually still working on it and that's whya they want you connected to the internet when you run 8 so they can do improvements and upgrades. LOL
While picking the brrains of the guys here at our CompUSA store, I asked the question of which is better.... 7s 32 or 64 bit version. The young lad I talked to said no one really needs the 64 bit version. 64 bit will do everything 32 bit will.... except run many of the older games. I know guys here do run SH5 on 64 bit 7 but not usre what they do. It could be Compatability Mode with Windows XP but not sure.
Good luck, and sink em all.
