How to install a new update safely

Follow

To ensure a smooth update of Microsoft Flight Simulator, it is crucial to check for outdated packages, corrupted saves, and profile/peripherals settings that may cause compatibility issues, leading to unstable performance and long loading times. We strongly recommend you follow the checklist below before installing a new patch and reinstall any additional content, plug-ins, or peripherals after installing the update to minimize any complications.

 

MOVE (OR RENAME) YOUR COMMUNITY FOLDER

Before updating Microsoft Flight Simulator, move your community package(s) to another folder or drive. If you do not have free space on your other drives, you can rename the folder to "Test_Community" instead. 

  • Depending on your platform, navigate to your Community Folder. By default, you'll find this folder at the following locations*: 
    • Microsoft Store|Game Pass version:
      • C:\Users\YourUsername\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages\Community
    • Steam version:
      • AppData\Roaming\Microsoft Flight Simulator\Packages\Community
    • Retail disc version:
      • C:\Users\YourUsername\AppData\Local\MSFSPackages\Community
  • Copy-cut (CTRL + X) the Community Folder
  • Paste (CTRL + V) the Community Folder on your desktop or a drive of your choice

*If you have installed the packages on a different drive than C: you'll need to look inside your custom installation folder instead.

 

UNINSTALL FREEWARE,PAYWARE, AND UNPLUG PERIPHERALS

WINDOWS AND MICROSOFT ACCOUNT SETTINGS

Missing system updates or mismatched Windows credentials can prevent you from updating the sim.

 

SIGN IN WITH YOUR MICROSOFT ACCOUNT

Sign in with your Microsoft account to sync your settings and purchases across all your devices.

 

Microsoft Flight Simulator does not allow license sharing. Each user must download the app on their own Windows profile and login with their own Microsoft account or gamertag to avoid problems with authentication, crashing, or missing entitlements.

If you have more than one Microsoft account and/or purchased Microsoft Flight Simulator with a different address than your main Windows 10 account, we recommend adding a Windows 10 user profile for the account used to purchase the game. 

To add or remove a Windows 10 user profile on your PC, follow the steps detailed in this article:
