Hi Jeff et al,
Apologies for late response however we did sort this out. We put in place another test system where we were able to do more investigation. After reviewing the code for the app, it ended up being a strcpy function issue which I think it out there as a known issue.
Once we updated that, we were able to start up the app on the new Win2012 Server using System Release 6.0 Build 271.
