It's not a good idea to install beta software or beta drivers on a computer you rely on every day. You should only install finished drivers, and don't update a driver at all if the existing one is working okay.
Uninstall the existing Catalyst Control Centre, then download and install the complete Catalyst Driver Package from your PC or laptop maker's website.
If it's a custom-made or home-built PC, download Catalyst Driver Package from the motherboard maker's website.
