Hi Jerry,
Thanks for this update.
Do i understand correctly you are running everything on one PC? Because i am running P3d en DP on different machine from DU. DP is giving me no problems. It is starting up properly and then waits for connection to DU.
Might be worth the try to deinstall EFB on the support machine and reinstall.
I do not look forward to a clean Win/10 install though
Just a question, do i need something like my licence code to reinstall or will it be saved over a deinstall/install on the same machine?
