Hi Rob-H-C, thanks for reply.
How do I establish which version I have.
Raymond, as you would expect, it's less than obvious. I think the correct method is to:
1/ open the Microsoft Store app on your Windows 10 computer
2/ On the Store app's home page you should see a down arrow immediately to the left of the three dots in the top right-hand corner of the screen. When you click on this down arrow it takes you to your Downloads and Updates page.
3/ Under the "Recent Activity" heading you should find Microsoft Flight Simulator listed with the version number in the 3rd column. Mine says: 1.11.6.0
If Microsoft Flight Simulator doesn't appear under "Recent activity" click on the "Get updates" button in the top right-hand corner of the screen. If an update for the launcher is available, it will appear here.

Good luck.
