Cannot install drivers past 7.12

[Romstar]

I have 2 2900 xt's in crossfire and everytime I try to install the drivers for 8.1 or 8.2 the display driver fails to install. I am using windows vista 64 bit. I have tried disabling and enabling crossfire before each installation. I have removed the entire drivers using driver cleaner pro in safe mode and then rebooting into normal mode and still no installation of display drivers in crossfire/no crossfire. I have the most updated bios/chipset drivers for my motherboard. All help is greatly appreciated.
