Please Update to the latest version of Camera Raw.
You can download it here: Adobe - Adobe Camera Raw and DNG Converter : For Windows : Adobe DNG Converter 9.1.1 9.1.1 is the latest for CS6
Hope it helps.
I have updated the latest ACR but PSCC is not showing the latest and not opening my raw files from my 7dii.
Go under help menu in Photoshop > about plugin > camera raw and let us know the version of Camera Raw
Also, could you please confirm if you receive any sort of error message when you try to open the raw files in Photoshop CC?
