To fix this:
- Uninstall any ATI drivers on your system.
- Run the CCC installer but I suggest canceling after it extracts the files.
- Navigate to: C:\ATI\Support\10-x_vista64_wi n7_64_dd_ccc_enu\Config
- EDIT InstallManager.cfg
- Change WorkaroundInstall=false to WorkaroundInstall=true
- Run Setup.exe and the CCC should install without a problem
