I have been operating MSFS without problems for around 3 months, but on the last attempt to launch it, having double clicked the desktop icon, nothing happened and an App appeared asking if I wanted to make changes to my device.
The App was titled "Microsoft Store Package Dependency Installer. Selecting yes brought up a page from Microsoft Corporation Gaming Services. There was no indication about what to do, so I rang MS Tech Support. They suggested that I carry out a Windows 10 update, but this did not resolve things.
On checking the MSFS forum, it seems that this problem has occured several times, but no solution is provided, except to uninstall MSFS and then reinstall.
I wonder if anyone on this forum has had the problem, and if the uninstall route is the only answer. Thanks, roytc.
