Install Msix Powershell All Users | Reliable Edition |

Before attempting a PowerShell deployment, the environment must meet specific criteria to avoid "Dependency not found" or "Architecture mismatch" errors.

Alternatively, via PowerShell:

对于 MSI 等传统安装程序，通常会提供一个 ALLUSERS=1 的参数。通过 msiexec /i File.msi ALLUSERS=1 这个命令，就能指定为一台计算机上的所有用户执行安装。 install msix powershell all users

Do not rely on relative paths. Use:

# 2. Verify file existence if (-not (Test-Path -Path $MsixPath)) Write-Error "The specified MSIX file was not found at: $MsixPath" return Verify file existence if (-not (Test-Path -Path $MsixPath))

Add-AppProvisionedPackage -Online -PackagePath $msixPath -SkipLicense

In modern Windows versions (1809+), simply running Add-AppxPackage as Administrator stages the package. However, to ensure it is provisioned (available for future users), you should use the Add-AppxProvisionedPackage cmdlet (see Method 2 below), which is the technically correct way for "All Users" deployment. Designed for security

In the evolving landscape of Windows application packaging, the format has emerged as the modern successor to MSI, AppX, and traditional EXE installers. Designed for security, reliability, and containerization, MSIX provides a consistent installation experience across Windows 10, Windows 11, and Windows Server.

For a paper titled "Install MSIX PowerShell All Users," Add-AppxPackage -AllUsers is the superior, modern choice as it satisfies the prompt by making the app available to everyone immediately.
