Hi,
i tried this but when i right click and go into properties there isn't a compatibility tab, there is only General, Security and Details!!!!! what can i do
to solve this solution which worked for me is
step 1 go to
C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static
step 2 find file CCC.exe
step 3 right click the file go to properties
step 4 in properties window go to compatibility tab
step 5 in compatibility tab you will find comparability mode check the check box and from drop down choose window 7 and click apply all done just restart your pc.
this worked for me for my dell inspiron 7520 with x64 windows 8 running on it.
hope it works ....
