Safe Mode FAQ



What is Safe Mode?

Safe Mode is a new feature that will allow players to launch the sim in a basic state to ensure stability.

When will Safe Mode activate?

The Safe Mode message box will appear every time the players are launching the game after experiencing a crash as long as the dev mode is not enabled.


Your last session of Microsoft Flight Simulator ended unexpectedly.
This may be due to installed 3d party content, out of date content, or incompatible drivers.

Would you like to continue in Safe Mode? In this mode, 3rd party content will be disabled.

If you do not have any issues when Safe Mode is active, then the issue is likely related to 3rd party content. This content can be updated or removed via the Content Manager or the community folder.

If the problem persists, try updating out of date content or incompatible drivers.
You can also check the forums, or contact customer support.




What does booting in Safe Mode do?

When launching Microsoft Flight Simulator in Safe Mode, mods from the community folder and third party content from the marketplace will be temporarily deactivated.


Do you know which add-on caused my last session to end unexpectedly?

There is currently no way to know exactly which add-on or combination of add-ons caused the crash. To find out exactly which add-on caused the crash, you will need to reactivate your Community and 3rd party content one by one.

I'm still crashing in Safe Mode, what can I do?

If the issue persists in Safe Mode, consult our article All versions - Crashing/CTDs issues

If the issue stops, you'll need to investigate which third-party software, mods, addons or community contents is not compatible anymore.


Can I manually boot in Safe Mode?

You cannot activate Safe Mode yourself but you can uninstall your Community and 3rd party content via the Content Manager.


Can I quit Safe Mode?

To exit Safe Mode, simply relaunch the game. You can also go to Profile > Content Manager > Not installed and update/reinstall the content of your choice while in Safe Mode, installing or updating content will re-enable content that has been deactivated by the Safe Mode
