Thanks but completely different topic there and I can't find any help either.

OK... Let try enabling the compatibility mode. Right Click on the Icon go to Properties go to Compatibility Tab and check on Run the Program compatibe with "Windows Vista" also check on the box which says Run as administrator see how it goes.

Good Luck,
Captain

Try this, AFTER running the uninstaller - Adobe CS4 Clean Script
