I have PS CS6 and when I supposedly install Camera RAW 9.7 I still can not read my raw files from Canon's new 5D MK IV camera which requires LR 6.7 & Cam Raw 9.7. I am on OS 10.11.6 and have LR 6.7 installed. When I go to: "about Adobe BR" it says 184.108.40.206
You can't install ACR 9.7 in PS CS6; you'll either have to upgrade to CC or use the latest version of the DNG Converter.

FYI, CS6 is only compatible with Camera Raw up to version 9.1.1
So there's no way of open 5D Mark IV Raw files in CS6.
You can open them in LR 6.7 and convert to DNG. Then open the DNG files in CS6.
