Images from Canon 7D mark 2 will not open in Photoshop CS6
Cannon 7D mark II has been included in the ACR 8.7. I would advise you to wait for the 8.7 camera raw to release.
In the meanwhile you can go to labs.adobe.com and download the 8.7 DNG converter and convert the files to DNG and then try to import.
