The last few driver updates either fail to install, install with no working Catalyst Control Center, and/or can't find .inf blah blah blah.
What I have been doing in uninstalling using the main uninstaller. Also running DriverCleaner.net and Driver Fusion to remove any other traces of ATI rubbish. (That part may not be necessary). I then uninstall the Display Adapter driver via Device manager to engage the Standard VGA Driver. Then right click the Standard VGA Driver and select Update Driver and manually navigate to C:\AMD\Support\13-1_vista_win7_win8_64_dd_ccc_whql\Packages\Drivers\Display and that should complete the install successfully with a working CCC. (Windows 7).
