I am having the exact same problem. I have a MacBook Pro with a Bootcamp partition running Windows XP SP 2 and every time I boot into windows, a lot of the Apple drivers (Keyboard, Trackpad, IR, ISight) fail with an error:
"Fatal Error During Installation"
I've even gone so far as to repair my windows install from the XP cd, but with no luck. The keyboard functions without the driver, but the function key does not, thus rendering my delete, home, end, page up, and page down buttons useless. VERY FRUSTRATING!
Does anyone know of a way to fix this? Any help is much appreciated!
