Installing Flight Simulator 2020 on Windows 11 from Xbox app - only allows install on C:

I found the solution.
You need to use NTFS as the file system.

I believe this shouldn't be the case as other game management systems don't require that. But if you are reading this and trying to install the files on an external drive be sure it's NTFS. exFat won't work.

Please try to change the folder permission on your E drive:

Press Windows + E to launch the File Explorer.

Navigate to the drive where you want to install the apps (in your case, it’s the E: drive).

Locate the WindowsApps folder. If you cannot find one, create a new folder by the same name.

Right-click on WindowsApps folder and select Properties from the context menu. Alternatively, you can select the folder and hit Alt + Enter to launch the Properties window.

Navigate to the Security tab and select Advanced.

Click on Continue in the Permissions tab of the Advanced Security Settings window.

Select Change to modify the permissions and grant access to the folder.

Click Advanced in the Select User or Group window.

Click on Find Now.

Select your user account from the list at the botton and click on OK.

Click OK in the Select User or Group window.

Click on Apply to save the changes.

Select OK in the Windows Security prompt that appears.

Finally, click OK to close the window.

After making the changes, restart the computer and check if you can now save the games to the selected drive.

If the game still can't be saved on your External SSD, please let me know and we'll proceed to further troubleshooting.

I would not recommend installing this to any usb based drive. This game is hard on hard drives

Hello, Paulo. Thanks for reaching out! My name is Lucas, and I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

Did you set your default install location to the E drive? If you didn't, please do:

Open the Xbox App.

Click on your Profile picture > Select Settings.

In the Xbox Settings, go to General Section > Game install options.

Click on the drop-down and change it to the E drive.

Also try changing the default location for new apps in Windows to your external SSD and then try installing the game again.

Go to Start (Windows Start) -> Settings -> System -> Storage -> Change where new content is saved (under 'More Storage Settings'). Change the setting "New Apps will install to:" to the drive you want to use.

Try it and let me know if it can be installed on your E drive.

If Xbox App still doesn't let you install your games on your external SSD, please let me know and we can proceed to further troubleshooting.

Hi Lucas
