Here is the description of the problem, I am able to install MS portion of the Sim, I click launch and go to a black screen. This does not change for 30+ minutes. I have uninstalled MSFS (multiple times), rebooted, nothing in the Community Folder

If I type flightsimiultor.exe from the Start Menu I do see an instance of flightsimultor.exe with zero bytes, I have deleted that file, rebooted and relaunched sim. Same problem.
