Just upgraded from 4 to 5, and Aero in Vista works fine. But in Windows 7 it says I don't have a compatible video card. My setup: Mac OS 10.6.2 Windows 7 RC build 7100 Processor: Model Name: Mac Pro Model Identifier: MacPro2,1 Processor Name: Quad-Core Intel Xeon Processor Speed: 3 GHz Graphics: Chipset Model: ATY,RadeonX1900 VRAM (Total): 512 MB
I think the same thing happened to me. I ran Windows Update after the installation and Windows found the correct drivers that I needed. Aero works fine now.
