It's the installation manager which is not working. I can eventually get to that screen, but when I click on Update, nothing happens. Yes, I have been patient, I've waited 10 hours before aborting.

OK so potentially I have cracked mine as the download has been going strong.

1. Take everything that you have go so far in your official folder out. What I mean is make a copy to your desktop.

2. Go to the app settings of msfs2020 and uninstall.

3. Reinstall via the store.

4. Start msfs via the store. Once you have started to the download pause and close the sim.

5. Add the copied official folder back in overwriting anything already there.

6. Restart the sim and then continue download.

For what ever reason I think this might have solved my issue

I might have spoke too soon. It got to 20GB download and then froze again. Reboot shows black screen again.

It worked fine before this "update"

Try using CC cleaner. Run the registry thing and keep going until nothing appears. So analyse...clean...analyse again.

Once done reboot and run the sim.

This has worked for me after 2 days of trying everything
