Adobe Reader XI on RDS 2012 R2

Just a quick post regarding a stupid issue I had this week with the latest Adobe Reader XI running on RDS 2012 R2. After installing it when trying to launch I would get this error:

The usual fix is to set the bProtectedMode registry key to 0. Problem is even after doing it the application still refused to launch.

Once I set the Compatibility Mode for the app to ‘Windows XP Service Pack 3’ I was able to launch it successfully. So in case you have the same issue make sure the registry key is there AND the app is set to ‘Windows XP Service Pack 3’ compatibility mode.
