and if all else fails u can go to device manager, and manually force "standard VGA" to take the 7970 drivers from the C:\AMD\Support\-insert catalyst package here-\Bin64 folder, once that is done u should be able to restart the computer and rerun the catalyst installer

.net and All my Mavimus V gene software is updated, ive used that method of manual forcing the driver install and it now detects the 7900 but the catalist still doesnt install see the grafic card afterwards and doesnt compleat the install.

Now what do i do ?
