Begin by creating a new Advanced Installer project, professional type or higher.

To create an MSIX, you must add to a new or existing Advanced Installer project, an MSIX/APPX build.

  • Go to the Builds page.
  • Add an MSIX build to your project by pressing in [ MSIX/APPX Build ] button in the top ribbon or by right-clicking in the Builds and selecting New > MSIX/APPX Build.

Before creating the package, it must be configured by choosing the output, package type, and platform target.

Configure the Output

  • Set the Output folder by pressing the [ … ] button and selecting a location on the computer.
  • Set the name of the MSIX package.

Configure the Package

  • Select version 1809 or higher as the minimum and maximum.

Target Platform

ImportantMSIX is supported starting with Windows 10 version 1809 and above; if you want to create an APPX select any version below 1809.

4. Sign the package

The package cannot be installed without being signed with a trusted certificate.
