$Store = New-Object System.Security.Cryptography.X509Certificates.X509Store( "Root", "LocalMachine" ) $Store.Open("ReadWrite") $Store.Add($Cert) $Store.Close()
This guide covers everything from basic installation commands to advanced options like provisioning for all users, handling dependencies, and silent installation.
To install an MSIX package using PowerShell, you can use the following command: install msix powershell
If you receive an error like "The root certificate of the signature is not trusted" , you must install the signing certificate before installing the MSIX.
Removal is straightforward:
Add-AppxPackage -Path "C:\Path\To\YourApp.msix"
If you want to register the package only for the current user (rather than for all users on the machine), you can use: $Store = New-Object System
If you encounter errors, check the package's integrity, ensure it's not already installed, and verify that you're running PowerShell with administrator privileges if needed.
Add-AppxPackage -Path "C:\Downloads\MyApp.msix" -ErrorAction SilentlyContinue Add-AppxPackage -Path "C:\Downloads\MyApp
The core cmdlet for installing MSIX packages is Add-AppxPackage . For line-of-business (LOB) applications not from the Microsoft Store, use the -Path parameter.
