MSIX Hero has been updated (both MSIX and app installer remote package) to version

Changes and improvements

  • NEW If the package declares support for MSIX Core, the information is now shown in the Dependencies tab. It also tries to show the actual name of the OS from the list of supported operating systems. To distinguish between these items, there is now a different icon for the Tested on section.
  • IMPROVED The default properties of MSIX Hero app installer file are now more liberal. The app does not anymore force the user to perform the upgrade, and the delay between update checks has been increased from 8 hours to 24 hours.
  • IMPROVED Search box displays a small “X” icon. Clicking on it clears the search box.
  • IMPROVED New package header (introduced in the previous release was always upscaling app logos. For some packages (including but not limited to Microsoft Visual C++ Runtimes) the icon were too small and looked jaggy after resizing. In this version, app logos are never upscaled.
  • IMPROVED MSIX Packages created by Advanced Installer that were using their custom proxy app AiStubElevated.exe were not showing the actual target path. This version has an extra recognition function built-in. Note, that the detection of Advanced Installer AiStub.exe proxy has always been functioning just fine.

Resolved issues

  • FIXED The dependencies view is now correctly showing Windows 10 2004 aka May 2020 Update. In previous releases, this upcoming update was only referenced by its version.
  • FIXED In previous versions there was an issue with the package selection not being appropriately reacting to filter and search key changes. On rare occasions, when searching for packages or filtering the list by type, a “limbo” selection could be maintained, affecting the UI and some commands. This issue is now resolved.
  • FIXED There was a little typo (lauch instead of launch) in the app installer editor. The typo is now fixed.

MSIX Hero has been updated (both MSIX and app installer remote package) to version

Feature highlight

  • NEW PSF fix-ups have now a dedicated tab. The new tab shows a pretty detailed, yet human-friendly overview of config.json and supports the following:
    • Redirection fixup
    • Trace fixup
    • Electron fixup
    • Other fix-ups are displayed but their config is treated as raw JSON file.

PSF tab is disabled for packages that do not use PSF.

By the way, this view is currently read-only. In one of the next updates, MSIX Hero will also get its own WYSIWYG config.json editor, which will reuse large parts of this new UI.

Other changes and improvements

  • NEW New header with basic package information in Package Expert and package sidebar.
Important properties like the package name, publisher and version are now always visible together with the product icon.
  • IMPROVED Algorithm for automatic calculation of required VHD size (MSIX app attach) has been improved in this build and accounts now for some NTFS pecularities.
  • FIXED In several dialogs, the main action button (for saving, creating etc.) was always disabled even on the confirmation screen. In this build, the button will be disabled as soon as the confirmation screen is shown.
  • FIXED Previous version displayed wrong version of package authoring tool for MSIX built with RayPack. In this version, the version is accurate.
  • FIXED Changing package selection was previously causing unnecessary second loading of manifest file. This has been fixed in this build.

A new version of MSIX Hero has been released, with the main focus on usability improvements.

Version contains the following changes:


  • NEW Package Expert dialog, allowing opening of MSIX files or manifests from disk. Press FILE > OPEN and choose Manifest or MSIX Package for a quick preview of package content, dependencies, PSF configuration and all features which were previously available only for already installed packages.
  • NEW Dropping .msix or .appinstaller files from the Explorer window opens them in a new window (maximum 10 at once) – this is just a handy shortcut of invoking Package Expert dialog or app installer editor.
  • NEW Command line support for opening .msix and .appinstaller files. If a single argument is provided, MSIX Hero tries to open the file based on its extension. This is yet another way of invoking the Package Expert.
  • IMPROVED Double clicking a package in the packages view opens a new resizable window with all information visible in the sidebar.
  • FIXED Fixed a bug in reading properties from certain AppxManifest.xml files.

Hello, here is another update to MSIX Hero. Main feature highlight of this new version is the ability to display Package Support Framework scripts. Also, this update fixes several issues and improves UI, especially the package sidebar.

Showing PSF scripts plus a new design of the package sidebar.


  • NEW MSIX Hero is showing PS1 scripts (a relatively new function added recently to the Package Support Framework). The sidebar shows the name, a few basic information about each script and it displays a link that can be used to open the script in a default editor.
  • IMPROVED New design of the package sidebar. Some tabs were moved around so that similar or related information are next to each other. Redirections (fix-ups), traicing information and other features of PSF are now displayed in the same tab. Similar visual tweaks have been done in the Dependencies tab.
  • IMPROVED Added keyword highlighting in the application list. Additionally, it is now possible to search for versions.
  • IMPROVED Several important values in the package sidebar (for example package full name or family name) are now selectable.
  • IMPROVED Changed the caption from Desktop Bridge and Desktop Bridge + PSF to Win32 and Win32 + PSF respectively.
  • IMPROVED The ribbon and tab items are now subtly animated when changing the selection.
  • FIX Fixed a bug with recognition of framework and UWP apps.
  • FIX After refreshing the package selection was not properly restored.
  • FIX Sorting by name was using internal name instead of the display name.
  • FIX Missing icon in UAC Dialog during self-elevation.

Additionally, this version has tons of internal changes for new upcoming features. Stay tuned for next updates 🙂

More information


Version is now available for download for new and existing users. The main focus of this minor update are improvements and resolved issues in the MSIX app attach VHD generator module.

  • NEW A new checkbox for automatic extraction of .cer file
  • IMPROVED Removed implicit dependency on Hyper-V PowerShell module.
  • IMPROVED Scripts for staging, registering etc. (if selected) are now saved in the same folder as the VHD and they are prefixed with VHD name for an easier identification.
  • FIX Fixed problems with getting correct package names in generated scripts

The new naming convention for scripts and .cer files produces the following structure:

Scripts and certificate file have now the same name base, equal to the name of the VHD image. This way it is easier to group the resources together, even if extracted to the same folder.

The article Creating VHD for MSIX app attach has been updated to reflect these changes.
