I have not tried to install or search for the display drivers through Windows Update, as I would have to first deregister the license key on my 2008 MacBook, and then install hundreds of updates through WSUSOffline so the computer can actually connect to the update server. I have also tried to install the display drivers manually from the Microsoft Update Catalog and from AMD's website, but neither work. I am using the same install DVD, which is a legitimate purchase from the Microsoft Store. When I had installed Windows 7 on my early 2008 MacBook, the initial installation of Windows 7 (not the Boot Camp software) started with a stretched screen, but halfway through the installation, the screen flashed and then the display looked normal, so I guess it installed the graphics drivers during the initial installation? This is not the case with the iMac. The display drivers in Windows after installing the Boot Camp software is just the generic PNP one that results in either a horribly low-resolution screen or one that is so stretched out that you can't read anything. The installation shows zero errors despite not installing the drivers properly, and no error messages ever appear that would indicate a problem with the installation.

Downloading the drivers from Apple's website using this link in the table and saving it onto a FAT/MBR external disk works, but when I try to install it in Windows 7, it seems to install the drivers, but it always misses the display drivers and occasionally the audio drivers, even after a restart or trying to 'repair' the program. Trying to download the drivers from Boot Camp Assistant gives me the error 'Can't install Windows Support Software because it is not currently available from the Software Update server' ( image). I have an old late 2006 20-inch 2.16 GHz iMac that I'm trying to install Windows 7 Professional on using Boot Camp 4.0.4 because Lion doesn't get 5.
