The reason I ask is because I attempted to install the ATI Catalyst driver 10.1, I'm running Windows 7 Ultimate 32-bit. When I tried to install it for some reason it does not install, it runs through but when I checked under Device manager the updated driver was not there. I then uninstalled it and I believe it might have even gone back to an earlier version, version 8xxx from 9/23/09. I think I remebered the original driver from Apple was version 9xxx from 11/09. When I try to update the driver through Device Manager I get a message that the latest driver is installed, even though there is the 10.1 version from 1.10 available from the ATI site.
I have no idea why I cannot install the current driver. I only tried to install the driver itself, not the whole software package.
