How to convert msix to msi?

Hello,

I am currently working with a Windows application packaged as an .msix file, which is used for connecting to Azure Virtual Desktops (AVD). I need to convert this .msix package to an .msi package. Additionally, I am looking for a way to convert a Microsoft Store app into an .msi package.

Challenges:

  1. Converting MSIX to MSI: I need a reliable method or tool to convert the existing .msix file to an .msi file without using Advanced Installer (didn't work).
  2. Microsoft Store App to MSI: I also need guidance on how to package a Microsoft Store app as an .msi.

If anyone is familiar with these processes, especially in the context of the windows app (yes there is an app named "windows app"), your help would be greatly appreciated.

Thank you!

    I doubt there would be such a methods. MSI is legacy, MSIX and Store are modern. You are going in wrong direction. For some Store Apps, you have the option to download offline installer. For MSIX, I would contact a vendor or someone who holds the original source/installation files.

    Point is, that MSI is not the only method. You also can script the installation. Just my thoughts, I might be wrong :)
