In Workbench there are Control Parameters that need to be entered (or checked if the Workbench or SQL server is changed). 

1. To install these for Greentree run the wb_LoadControlParameters.sql for the Workbench version. (Make sure in the table that the UseForMDE is set to True)



2. In Workbench fill (or change) in the Control Parameters for Greentree 



3. It is the MDE that holds the code for the interface. If FREE works on the clients PC then the Workbench interface should work, as long as the interface version is correct on the MDE. In Workbench look at the Help > About Workbench screen.


4. Check the MDE in the Workbench\APP\Live folder is the same as the MDE being used by the Client workstation.
