There was a failure to validate setting CTLRUSERS in validaton function ValidateUsers.

You might get that error while installing SQL server 2012, it's when you select a non domain user while in the Distributed Replay Controller step.

You need to choose a domain user or no user at all...Hopefully they improve that error MSG to a meaning error in future releases :)
