Windows doesn't even know what to do with this "appinstaller" file. Any way to convert it to an exe? Or what are the barebones components needed to install these types of applications?
You could try PowerShell: Code: Add-AppxPackage -Path "path\to\appxfile.appx" Same command should also work for .eappx, .appxbundle, .msix and .msixbundle packages...
