I ran Windows Upgrade Advisor Beta, and passed all 4 system requirements, but it said that I needed to update my graphics card driver. I have a Nvidia Geforce 8700M GT (512 MB). I upgraded to the latest driver, but the advisor says that it still is not compatible with Windows 7! I'm pretty sure my graphics card won't have any problems, but why does the advisor still say "incompatible"? Also, I want to know if I am able to upgrade from Windows XP Professional 32-bit to Windows 7 Professional 64-bit via clean install. I have a Core 2 Duo (2.4 gHz). Thanks.
