PRB: Error Message 3633 "Can't Load DLL '?????L?' " When Running Deployed Application

When you deploy an application that uses the CreateWorkspace method to create an Open Database Connectivity (ODBC) WorkSpace, the application raises one of the following errors:

When the call to CreateWorkspace creates an ODBC WorkSpace, it uses ODBCDirect, which is dependent on the Remote Data Objects (RDO) Msrdo20.dll file. Because there is no actual Reference to ODBCDirect in the project (just the type of call that is made in code), the Package & Deployment Wizard (PDW) does not know to include the Msrdo20.dll file.

Add the Msrdo20.dll file to the Package. There are two different methods to accomplish this when running the PDW:

1. If you are presented with a DAO Drivers screen, move ODBCDirect over to the Included Drivers column. This includes the Msrdo20.dll file.
   
   From the Included Files screen, click the Add button and manually add the Msrdo20.dll file to the Package.
2. From the Included Files screen, click the Add button and manually add the Msrdo20.dll file to the Package.

This behavior is by design.
