App Installer package-family and ms-appinstaller deployment note
For App Installer / Windows Package Manager troubleshooting, Microsoft documents the package family as Microsoft.DesktopAppInstaller. You can verify the installed App Installer version with (Get-AppxPackage Microsoft.DesktopAppInstaller).Version. If App Installer is present but needs to be re-registered, Microsoft lists Add-AppxPackage -RegisterByFamilyName -MainPackage Microsoft.DesktopAppInstaller_8wekyb3d8bbwe.
For MSIX/App Installer deployment links, do not rely on browser one-click install links using the ms-appinstaller:?source= URI scheme; Microsoft says that protocol is disabled by default as of December 2023. Link directly to the .appinstaller package instead, or use your normal enterprise MSIX deployment path.
