Hello
First try reinstalling .Net framework
Download details: .NET Framework 3.5
Then if above don't work i encourage you to install Ati tray tool from here
ATI Tray Tools 1.3.6.1042 download from Guru3D.com
If you don't know even what PCIe is it will be harder for you in the beggining to work with this little program but is much more flexible than CCC and it should work from first shot.Here is the support forum and a little guide for it:
ATI Tray Tools Generic Discussion - Guru3D.com Forums
I hope this helps
good luck
