How to resolve run-time error#430: Class does not support Automation or does not support expected interface?

I install virtual windows 98 (vm98) inside VMware Workstation, use PCMover to move all application from a physical Windows 98 (ph98) to vm98. When I launched my application (myApp), it runs into the above error message and closes by itself. This question is related to the following question: https://www.experts-exchange.com/Software/Virtualization/splitPoints.jsp?qid=24729872&aid=25357698
I have little knowledge of myApp due to long history reason. My goal is to make myApp run in vm98 so I can preserve myApp forever!
Q#1. What is the cause?
Q#2. How to find out what is missing? ph98 is still running but dying. So it is still possible to dig into the working machine if someone knows the direction.

It's not financial report, not FRx either. It's a VB program accessing MS Access DB and MS SQL DB.
Any way to debug like a developer does?

After installing Microsoft Data Access Components 2.8, it does not have the same error any more. But the application is not doing the job - not processing the batch.
