"Installing MDriven Server on Windows" - cannot access local Turnkey - mdriven

Question

I have tried to install MDriven Server and Turnkey according to the page "Installing MDriven Server on Windows" (https://wiki.mdriven.net/index.php/Installing_MDriven_Server_on_Windows) and the Video (https://www.youtube.com/watch?time_continue=722&v=q0ppL5sMPGg).
Installed versions are MDrivenServer_20190411.zip and MDrivenTurnkey_20190415.zip
The PC is a Windows 2019 Server (also tried on Windows 10 Workstation, results are identical!).
I can open the MDriven Server pages (https://MyServer/MyTurnkeyApp/__MDrivenServer) everything looks fine, i.e.:
I created a new "a" user with a known PWD according to the Video
DB connectivity/check/evolve is fine
https/Self-signed SSL certificate works as expected
MDrivenServer works as expected and as described in the article & video!
However I cannot go to the Turnkey pages (https://MyServer/MyTurnkeyApp).
I always get an error message:
Server Error in '/MyTurnkeyApp' Application.
Not able to start, check the CurrentVersion - is it set? Check that the app is Started and not Paused. Check that the Version is in DatabaseUpdated state.

Any idea what's wrong?

Check this answer: MDriven Server installation
I think it is the same issue.
You have no model uploaded to mdriven server
or the model is not selected as current
or the app slot A0 is not started in mdriven server.
