lessmsi is a Windows utility with both a GUI and a command line interface for viewing and extracting the contents of Windows Installer (.msi) files. It also integrates with Windows Explorer for right-click extraction and includes an MSI internal database table viewer.

Use cases

  • extract files from an msi installer
  • view contents of a windows installer file
  • extract msi files from the command line in scripts
  • inspect msi database tables
  • right-click extract an msi in windows explorer
  • pull driver or payload files out of an msi package

When to choose

  • you need to unpack an .msi without running the installer
  • you want to automate msi extraction in scripts or CI
  • you need to inspect the internal tables of an msi file
  • you want explorer right-click extraction on windows

When to avoid

  • you need to create or author msi packages rather than extract them
  • you need a cross-platform msi tool for linux or macos
  • you need to modify or patch msi files
