I followed the readme text, but suddenly I'm told I need to add .Net 2.0 or better. I don't use .Net, I just want to load the latest ATI driver, and I understood that Driver Cleaner can help me clear the silly message, "be sure you have a standard VGA driver" upon trying to load the latest Catalyst driver for my Radeon 9700. Do I absolutely have to do all that .Net downloading to use Driver Cleaner for my purpose?
