Tim, Server 2012 R2 should not be an issue, I suspect the real root cause was more likely related to a Group Security Policy running on the server or the service account etc. would be my best hunch on this one. You do NOT want to use the 'production' QVS.exe either, you should always grab a copy of it and place it in a different folder and run the script from there too, that could be the other thing you were trying to do that was not working.
