MSIX Hero 1.0.16 – signed MSIX app attach scripts and more

A new minor update of MSIX Hero is available. This build improves the experience of MSIX app attach (UI and command-line driven) and fixes a few spotted issues. The update is highly recommended.


  • App attach scripts are now digitally signed.
  • Because of the previous, the configuration of package(s) for app attach has been moved to a separate JSON file app-attach.json, which is then accessed by staging and registration scripts. In order to make adjustments (like changing the MSIX junction point path) edit the JSON file directly. Below is a typical file structure that is created (either from UI or from MSIXHeroCLI.exe):
  • All MSIX app attach scripts have now constant names (for example stage.ps1) and do not contain the name of the package anymore. This has the following benefits:
    • It is easier to run them manually by just typing a few letters in Terminal window
    • This is also now semantically correct, as the scripts are now effectively the same for all packages, since the configurable data has been moved to the JSON config.
  • The content of the scripts for app attach has been generally improved in terms of code formatting, and a missing dismount routine (also not present in templates on MSDN) has been added to the destage.ps1 script.
  • Staging script had previously duplicated curly braces, which could cause an error returned by mklink. The issue has been fixed in this version.
  • Speaking of mklink, its exit codes are now checked by the staging script. Non-zero exit code will break immediately.
  • The dialog for certificate extraction can now trigger self-elevation (UAC) in case the checkbox for trusted store is checked.
  • In the same wizard, a shield has been added to indicate possible elevation.


The app will be updated automatically in a few hours if you installed it from app installer file. New users can download MSIX Hero from the Download page.
