Windows Installer PowerShell extensions project now available on CodePlex

Heath Stewart recently wrote a blog post at that introduces a new project that he published on CodePlex - the Windows Installer PowerShell Extensions (also known as PSMSI) project.

The initial version of this project, located at, contains cmdlets that can be used within PowerShell to query product and patch information for installed MSI-based products.  I've talked to Heath about this project, and his longer term vision includes many additional cmdlets so that these extensions can be used for a variety of Windows Installer troubleshooting tasks.

If you use PowerShell at all and/or are involved in setup development or troubleshooting, I encourage you to take a look at this project to see if you can use these extensions (and possibly contribute to enhancing them as well).
