Cmdlets to Manage MSI Packages

PowerShell 2.0 and later

Anyone who needs to manage MSI installer packages may benefit from an open source project found here: http://psmsi.codeplex.com/.

Simply download the PowerShell module – it comes as an MSI installer package itself. Make sure you unblock the MSI file before you install it (Unblock-File). Otherwise, Windows may refuse to install it.

Unfortunately, the module installs itself in a highly unusual location (AppData\Local\Apps\...), and extends $env:PSModulePath so PowerShell can find the module. This is why you need to restart PowerShell after module installation, because PowerShell will not pick up the changes to $env:PSModulePath.

This is how you can list the new MSI-related cmdlets:

PS> Get-Command -Module MSI
