Can't install MSIX package with powershell


The problem

I am trying to install a .net core 3.1 wpf app onto a windows 2019 server using msix as the method of deployment. The windows server is up to date and should support msix, but will not install any msix package I create using the powershell command Add-AppPackage. The packages will install on windows 10 machines if you click on the .appinstaller file and use the gui, but they will not install on the same machine if you use powershell.

What I have tried

  • I've went through this troubleshooting page to no avail.
  • I have tried different msix packages
  • I have tried using a local file directory
  • I have tried running as administrator


This is an example of what I am trying to install: appinstaller file Running the .appinstaller file will correctly install this uwp app. However, this will not work:

Add-AppPackage .\TestUwp.appinstaller

Error Message

This is the error message the powershell script outputs:

Add-AppPackage : Deployment failed with HRESULT: 0x80073CF0, Package could not be opened.
error 0x8007000D: Opening the package from location TestUwp.appinstaller failed.

When you use:

Add-AppxPackage .\TestUwp.appinstaller

The path will be mapped to the positional parameter -Path. This parameter is designed to specify the path to the app package. But you are not installing the app directly. You are using an app installer file. To install from that, use:

Add-AppxPackage -AppInstallerFile .\TestUwp.appinstaller

With this command, I was able to install your package successfully.
