Please install Camera Raw from the following link : Camera Raw installer for Adobe Photoshop CC and CS6
Restart the Applications and let me know if you are able to access Camera Raw or not.
No, it didn't work for the PC and now I'm going to try it on my Mac when the download finishes. It said that it could write the file to the HD and aborted.
Here's the log entry that I got (and I didn't download the one for CS6 but for CC):
Extracting to "C:\Program Files (x86)\Adobe\Adobe Photoshop CS6\"
Use Path: yes Overlay Files: no
Error: Access is denied.
Cannot create C:\Program Files (x86)\Adobe\Adobe Photoshop
Administrative privileges may be required.
Severe Error: File creation failed.
I am the administrator on this computer.
