How do I file a formal complaint?

To make a formal complaint, use Microsoft Support first, then use the formal complaint channel if needed:

1. Go to Contact Microsoft Support and enter the problem.
2. Select Get Help.
3. If more help is needed, select Contact Support to be routed to the best support option.
4. For a formal complaint, use Microsoft’s concern reporting page: https://www.microsoft.com/legal/compliance/sbc/report-a-concern

For the installation issue itself on Windows 11, the supported self-service steps in the provided guidance are:

1. Restart the PC: Start > Power > Restart.
2. If the app appears in Start > Settings > Apps > Installed apps, select it and open Advanced options.
3. Select Repair.
4. If the issue continues, select Reset.
5. If needed, uninstall it from Start > Settings > Apps > Installed apps > Uninstall.
6. If the game was purchased through Microsoft Store and install options are missing or stuck, reset Microsoft Store:
   • Press Windows key + R
   • Enter wsreset.exe
   • Select OK
   • Wait for Microsoft Store to reopen automatically
7. Check whether the game is compatible with the device in Microsoft Store, because some apps and games work only on specific device types.
