go into the control panel -> uninstall a program,
look for the ati catalyst install manager and click on it,
then click next, check uninstall(top most option) and click next,
then check customize and click next, then check the catalyst control center (top most option and make sure it is the only one that's checked) click next to uninstall, after that go down the ccc on ati web, just the ccc, no need for the package, then install it, hmm try to click on customize and check ccc when install, dont use the express. hope it help.
