I am trying to install Catalyst 8.7 but every time I try to install it, it tells me that the "Display INF Driver File" cannot be found. I also tried to do a manual install by going into the device manager, but the same error comes up. The only Catalyst drivers that works is 8.8, but I don't want to use 8.8 because well, it sucks. I am running Vista Ultimate x32.
