You can install the old CCC by downloading an old driver(10.12 WHQL is the one I used) and selecting the advanced install option. Then just select to install just the CCC and it'll overwrite the newer one. I had to do this because the new CCC in 11.1 didn't want to load half the time. 11.2 fixed all that though.
Alternately, if you already a driver with the old style CCC, when you download and install 11.2 go to the advanced install option and un-check CCC. Then it shouldn't update CCC while giving you the new driver.
