Fortis To DW migration Error

We are trying to do a Fortis to DW and when running the migration tool, we get the following error "An error occurred please contact the administrator with the following information: Exception has been thrown by the target of an invocation." What does this mean?

Good Afternoon Bernie, 

What is the version of Fortis and DocuWare that you currently have?

When do you encounter this error message? 
For further troubleshooting, can you please have a support request created, then we can continue from there.

Thanks for answering so quickly. DW is 6.12 and I noticed that Fortis shows 6.10 even though we upgraded to 6.12 a while ago. Inflo and Scripted mgr show they are at 6.12. I figured to post here before calling our Service Reps cause it takes them forever to get back to us.

No problem. 
That's an interesting find, and could be the reason why we're seeing this error message.
Can you verify that the fmconfig.txt file shows the correct version for Fortis?
Maybe some files from the Fortis directory were not upgraded correctly.

Went to Fortisdt/sysdata and the fmconfig.txt file says V 6.12.0

Hi Bernie,
