Thank you Aaron for sharing.  We ended up doing the same.

This definitely needs a fix.  Had we not had alternative way of getting into the machine, it was going to be a long drive.

HI.  We are having the same problem.  Guest info returns a valid screenshot 100% of the time and the keyboard inputs work correctly remotely.  Fortunately we had a competitors software on the system which worked.

We're running:

Windows 10 Pro for Workstations (10.0.18362)

Intel(R) Xeon(R) W-2104 CPU @ 3.20GHz (4 virtual) (X64)

NVIDIA Quadro P400, 2GB, 3 Dis playPort (5820T)

Has anyone found a 'software display emulator' that works?  Any suggestions would be greatly appreciated.
