This is a utility with a graphical user interface and a command line interface that can be used to view and extract the contents of an MSI file.

Usage

To extract from the command line:

 lessmsi x <msiFileName> [<outouptDir>]

For more command line usage see CommandLine.

Installation

Install via Chocolatey (or download a zip).

Features

Windows Explorer Integration

Lessmsi also integrates with Windows Explorer so that you can right-click on a Windows Installer file (.msi file) and select "Extract Files" to extract it into a folder right there:

GUI

In addition to allowing you to extract files from the command line and from inside Windows Explorer, lessmsi has a graphical user interface that allows you to view detailed information about any MSI file.

MSI Table Viewer

Windows Installer (.msi files) are based on an internal database of tables. Lessmsi features a viewer for those tables. Useful for people who work a lot with installers.
