Retrieving MSI file information with PowerShell

Jan 26, 2023

An MSI (Microsoft System Installer) file is a format specific to Microsoft used for installing applications on a Windows computer.

An .msi file contains information about the application to be installed, such as the version, the publisher's name, the necessary files, configuration settings, etc. The information in the MSI is sometimes displayed in the Properties > Details. However, some MSI files contain no information about a property.

For example, the AutomatedLab installer MSI file does not contain any information about the version:

Some information about an msi file may be empty

In order to obtain this information, I developed a small PowerShell script to retrieve the information from an MSI file:

  • FileName: name of the MSI file
  • FilePath: full path of the MSI file
  • Length (MB): size of the MSI file in megabytes
  • ProductVersion: version of the product (application) contained in the MSI file
  • ProductCode: GUID generated by Windows Installer to identify the installed product
  • ProductName: name of the installed product Manufacturer: name of the product publisher
  • ProductLanguage: code of the product language
  • UpgradeCode: GUID representing a set of related products.

It also contains the information visible in the Details (SummaryInformation).

If a property does not exist in the MSI, the returned object will still have this property but it will be empty.

The script is available on my GitHub.

To run it:

# Load the function
. .\Get-MSIFileInformation.ps1

# Type the file in the parameter -FilePath
Get-MSIFileInformation -FilePath C:\temp\AutomatedLab.msi

The result is as follows:

FileName        : AutomatedLab.msi
