I have Photshop CS6 Extended but when I click on the .cr2 which is the RAW file I keep getting an error message "Could not complete your request because it is not the right kind of document"
I have tried installing the camera raw plugin
Photoshop Camera Raw 7.1
Installation failed. Error Code: U44M2P7
You don't say what camera. I assume it's a new one that Camera Raw needs an update to recognize.
If Help - Updates fails to update Camera Raw, among all the other components, visit the appropriate link below and do a manual installation...
Also you may want to verify if your camera’s RAW format is supported yet.
