Server could not register with the back-end since a version mismatch was detected.

Version mismatch back-end "%1", database "%2" using the connection string of 
%3. The service will not start until this problem is resolved.
Cause: The database schema and the Server were updated by different installation packages.
Resolution:
Ensure both the Server and back-end were installed or modified by the same installation package.
