The MSIX Packaging Tool is vital for IT professionals and developers, enabling them to repackage existing desktop applications into the MSIX format. The tool offers both an interactive UI and a command line for conversions, allowing the conversion of an application.

The latest public release of the MSIX Packaging Tool is Version 1.2024.405.01. This version includes enhanced PSF support for process, dynamic library, environment variable, and middleware fixups. It also provides improved guideline support for utilizing the PSF Fixup feature in the tool.

Key Features

The MSIX Packaging Tool enables you to do the following tasks:

  • Package your favorite application (msi, exe, App-V 5.x, and custom scripts) in the MSIX format by launching the tool and selecting the Application package icon.
  • Create a modification package for an MSIX Package by launching the tool and selecting the Modification package icon.
  • Open your MSIX package to view and edit its content/properties by selecting the Package editor icon, browsing to the MSIX package, and selecting Open package.


To install the MSIX Packaging Tool from the Microsoft Store, you need to have Windows 10, version 1809 (or later), participation in the Windows Insider Program (if you’re using an Insider build), a valid Microsoft account (MSA) alias to access the app from the Microsoft Store, and administrator privileges on your PC to run the tool.

You can also install the MSIX Packaging Tool from the WinGet command-line tool using the command: winget install "MSIX Packaging Tool". The tool can also be directly downloaded for offline use.


The MSIX Packaging Tool is continuously evolving, with Microsoft investing in supporting the conversion of more legacy applications to the MSIX format. The tool now supports packaging portable apps into MSIX format, enabling them to be app attach ready. It also monitors child processes created by the original application during the capture process, helping increase the accuracy of the conversion.

With these updates and more, the MSIX Packaging Tool is becoming an increasingly powerful tool for IT professionals and developers alike.
