I have now tried to develop a new database, Windows Access 2007, and have the same problem: "MISSING Utility.mda." So, it is not just a conversion problem. Converted programs, 2003 to 2007 work just fine. However, any attempt to do updates are aborted with the same message: "MISSING Utility.mda." I loaded MS Access 2007 on my wife's computer and get same error messages there, not with conversions but with new developments.
