Thanks, the detail in your replies always amazes me. Looks like the DB provider doesn't support a VistaDBv4 database so I was attempting an upgrade to FileVista 6.8 (from 4.x) first to get to a v5 database. Below is the error I get during the upgrade, corrupt database?
System.InvalidCastException: Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'.
