Found the answer to your problem.

Anytime you are using the Bound Data Controls you need to deploy VB5DB.DLL for your app to work. This file is not normally deployed. All the AutoOSUpdaters and ********** will be updated to deploy this file along with the VB Runtime files.

If you are using Inno Setup add this line to your script:

Source: e:\server data\randem\develop\vb 6 redist files\vb5db.dll; DestDir: {sys}; Flags: uninsneveruninstall sharedfile

Of course change the source location to match where it is actually located on your system.
