This has happened a couple times in the past drivers, I would install the new drivers and CCC would magically disappear from my HD; only this time CCC stays, but with less settings, and the new app disappeared.
It was there when I installed the first Crimson driver, but after the second one.
Tried clean installing it, still no luck.
Please make sure you have the latest Visual C files installed and updated, download here. Use Windows update afterwards to ensure everything is up to date.
If the issue persists, i would recommend waiting for the next Crimson drivers which we hope to have available soon.
