I currently have Camera Raw 188.8.131.52 with PSE 12, but I need Camera Raw 8.3 to support the Sony A7r. What do I need to do?
Normally, go to Help -> Updates and the new ACR will be be installed.
However, that will not work if you are using XP or Vista.
Thanks very much for taking the time to help. That did exactly what I was looking for, much appreciated!
