Have you tried to download and install the drivers directly from AMD's website?
Try downloading from here: http://support.amd.com/us/gpudownload/Pages/index.aspx?src=CCC-CheckForDriverUpdates
The only reason you shouldn't be able to install from those is if you aren't logged in with administrater rights.
yeah, I have. I download the application- and it doesn't allow me to install CCC because I have a Toshiba laptop.
Stated from website:
"■Toshiba notebooks (please check with your notebook OEM for driver support for these notebooks)
Too bad my OEM hasn't provided one!
