A client on GP 2010 had just installed Professional Service Tools with the primary intent of running the Copy Company function to transition from test to production.  The utility was failing with the error:

Unhandled script exception:
[Microsoft][SQL Server Native Client 10.0][SQL Server]Could not find stored procedure ‘XYZ.dbo.eeCompanyCopy’.

The cause was that the end user had set up their own ODBC DSN and did not clear the check boxes for ‘Use ANSI Quoted Identifiers’.  Clearing the ANSI flags on the connector allowed the utility to run without error.
