Workflow Demo on Windows not working

Hello,
I really TRIED hard to get the demo working, but running the demo data the app always throws an error about an invalid path for the access database. On design time the ADOConnection connects without problem.Tried 32 and 64 bit ODBC, red hints on microsoft website etc. etc.

Any hint, what I'm possibly doing wrong?

Thanks for reading!

Everything is working fine here, clean Windows computer, clean Delphi install, clean TMS Workflow Studio install.

What exact error are you getting? Do you have the .mdb file located in subfolder Demos\db\access?
