When I delete %USERPROFILE%\AppData\Local\ATI\ACE folder the CCC return to work properly for a couple of days.

Who can help me?

Same problem. Switchable graphics do not work at all, and as time goes by not only is nothing fixed but settings are now not even being saved when you try to change them.

Buying this laptop was the biggest mistake i have ever made
