I would greatly appreciate any guidance on where to go with this. I purchased a HD6670, and, while I can get the drivers to install, I cannot get the CC to install, it hangs no matter what I try. I am running Win 7 X32, the card manufacturer is Sapphire. Here is what I have tried so far: Uninstalled drivers, restarted, used driver sweeper in safe mode, tried to install drivers in safe mode, gone into the registry and removed all keys related to ATI, removed via device manager, disabled all security software, turned off UAC, ensured their were no conflicting drivers, verrified running .net 3.1, verified that the driver was the correct version (12.6). The end result is the same, when installing, the install hangs at the half way point. Their were no hardware or software changes prior to this other then upgrading my PSU. Please help!
