Microsoft Store - Download and Installation issues - Basic Troubleshooting


If you are experiencing any of the following issues:

  • You're still unable to download, install or update the sim after completing the Download & Installation issues (Microsoft Store) Part I - Checklist
  • The app "uninstalled" itself but the packages are still on your computer
  • You see the message "This app can't open. Check the Store for more info about Microsoft Flight Simulator. Get help with this."
  • Nothing happens after clicking the "Play button" in the Microsoft Store but there is no error message
  • You receive the error message "Flightsimulator.exe has stopped working."


First, please ensure that your security software isn't blocking the launcher, then reset the App and the Microsoft Store cache and reinstall Gaming Services. We also recommend installing the Xbox app to authenticate your game. Finally, run chkdsk to detect and repair logical and physical issues that may be affecting your drive.



Antivirus and malware checkers can close down or prevent certain applications from launching, even if they are legitimate and safe.


Open Windows Defender and turn off real-time protection.

  • In the Cortana search box, type "Windows Security"
  • Open "Windows Security" > "Virus & Threat protection" > "Manage settings"
  • Disable "Real-time protection"


Stop Windows Defender from blocking Microsoft Flight Simulator by adding the launcher to the exclusions list

  • Go to Start  > Settings  > Update & Security  > Windows Security > Virus & threat protection.
  • Under Virus & threat protection settings, select Manage settings, and then under Exclusions, select Add or remove exclusions.
  • Select Add an exclusion, and then select Microsoft Flight Simulator. A folder exclusion will apply to all subfolders within the folder as well.

Temporarily disable your security program(s) before launching Microsoft Flight Simulator

False positives occur when your antivirus software incorrectly identifies safe software as malicious. If your antivirus or anti-malware falsely flagged Microsoft Flight Simulator remove the file from quarantine if necessary then whitelist Microsoft Flight Simulator. To do so follow the instructions from your manufacturer.

  • Sample of Virus & malware checkers that have been known to prevent Microsoft Flight Simulator from launching:
    • Malwarebytes
    • Norton & Norton Utilities Ultimate
    • Trend Micro Maximum Security
    • Comodo Antivirus
    • Sophos
    • Emisoft Anti-Malware
    • Avira
    • Avast & Avast Cleanup
    • Bullguard


If the sim launches normally after disabling your security program, whitelist Microsoft Flight Simulator before turning the program back on. To do so, refer to your security software's support website.



Depending on your version, follow the instructions from our knowledge base articles.
