All Users: Install Msix Powershell

Do not rely on relative paths. Use:

Before running the commands, ensure you meet these requirements: install msix powershell all users

$currentPrincipal = New-Object Security.Principal.WindowsPrincipal([Security.Principal.WindowsIdentity]::GetCurrent()) if (-not $currentPrincipal.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) Write-Host "ERROR: This script must be run as Administrator." -ForegroundColor Red exit 1001 Do not rely on relative paths

The script utilizes the [Security.Principal.WindowsPrincipal] check to enforce Administrator rights. The -AllUsers parameter is the critical switch here; without it, the package installs only for the currently logged-in user context, even if run as Admin. Add-AppxPackage -Path "C:\Path\To\YourApp

Add-AppxPackage -Path "C:\Path\To\YourApp.msix" -Register -ForceApplicationShutdown
