I cannot get 11.10 to install PERIOD.
It wouldn't install over 11.9, so I uninstalled 11.9, rebooted, ran Driver-sweeper, rebooted, reinstalled 11.10 - FAILED. Re-downloaded 11.10 and tried all this again...fail.
Reinstalled 11.9 right then and it went through the first time.
Sounds like an installer error in the 11.10 package.
no i believe driver sweeper cleans out some .dll files tha u need to install Cat drivers. I did that once with win7 and it totally screwed up my installation. Driver sweeper, uninstalling, and safe mode, all that nonsense was for the WinXP days. now, from AMD themselves, u just instally the driver after downloading it over the old drivers, the cat installation will automatically uninstall the old ones and do all is necessary. its 2011, installation is very simplified now and all those old school steps of uninstalling, driver sweeper, safe mode, yadda yadda totally screw up ur installtion.
