Hey guy's R4GE VipeRzZ here, and today I'm going to show you how you can fix the. This app package is not supported for installation by App Installer because it uses certain restricted capabilities. That causes the error, cannot open app package. When you try to run MSIX files in Windows.

In this video I am using Windows 11, but it should be the same for Windows 10. In order, to fix the problem we will open up the Microsoft Store and will then updated the Microsoft Corporation App Installer. Once this has been done you should then be able to run the MSIX file.

In the video I am successfully able to installed Microsoft Teams, by running the Teams for Work and School MSIX file.
