I just installed Catalyst Control Center and can't find how you actually open it anywhere. I have searched my computer. I find lots of info on google on how to install and use but nothing on opening it. I guess I am stupid.
Reinstall it. Maybe you didn't select auto install and in select install component you only select install driver, or installation of the driver component is successful but others not, or you only download the driver component to install. Check the installation log at the end to make sure everything is installed correctly.
