This has been the most effictive advise with getting my CCC to work, after uninstalling everything using the driver sweeper and all that, :
While UAC is turned off (Vista/7 only) navigate to the "C:\Windows\Assembly" folder and delete any assemblies which have the public token key "90ba9c70f846762e". It is possible that you won't find any, but check it.
