MSIX Hero 3.1 is now available for download. This is the first official update in a while and brings new features, enhancements to existing features and bug fixes.
Browse packages by folder
This update introduces an intuitive way to analyze directories filled with files or subdirectories. Now, you can easily identify and preview MSIX files and their associated manifests in a visually appealing and informative manner.
Previously, it was possible to view packages in user mode and machine mode (packages installed system-wide). Now there is a third option, which allows the user to simply browse a selected folder. MSIX Hero will scan the folder and display all packages found, regardless of their source format (packed, unpacked) and installation state (installed or not).
New drop-down menu with the ability to toggle between applications installed per user, installed for all users, or simply present in a selected directory.
To make this feature possible, there have been significant changes to the Filter menu.
The user/all users toggle has been removed from the filter menu, and filtering and sorting have been swapped.
The little button next to the search menu is no longer a toggle, but a popup that activates the mode selector.
Additionally, you can browse a directory by simply dragging a directory from your Windows Explorer onto the MSIX Hero window.
Sample use cases:
Browse directories to locate and inspect all MSIX files, complete with detailed metadata for better understanding.
Quickly identify MSIX packages that are already installed (or which are not).
Preview build artifacts directly from your project folders, ensuring everything is in place and ready for deployment.
And more. Discover how this feature simplifies your workflows, whether you’re managing application builds or organizing complex file structures.

MSIX Hero 3.0 is now available for download. This is a major release with many new features and internal changes.
Multilanguage support
MSIX Hero UI is localized and translated to German and Polish. You can change the language in the Settings menu, and at first start MSIX Hero will choose the best match from the list of supported languages (based on the current system UI).
New card-based UI
The UI has been reworked – many settings that were previously buried or hidden are now available, often without an extra click. For example, this is the default view for a package:
Some other areas that are heavily affected by the new design principle are the event viewer and the PSF content browser. Be sure to check them out!
App pinning
Installed applications can now be pinned and unpinned. Just click the star icon next to each installed app:
Shared Package Container
It is now possible to create XML files or deploy Shared Package Containers directly. MSIX Hero GUI provides an easy way to set things up, including selecting installed packages, reading from installable files, reordering, etc. All these options are now available in the CLI interface as well.
Certificate and timestamp validation
Wherever there are signature options, there is now a new button to validate the data.
The validation process ensures that end-to-end signing works. It performs basic certificate validation, timestamp server settings, trust status, and more.
Improved display of events
In the event details section, typical Win32 errors are now displayed in a human-friendly form, with additional explanation where possible. For example, the following is displayed for an event that describes a situation where an existing package is reinstalled, but with a different content.
The list of events has been redesigned to show more information at a glance:
Advanced options for appinstaller creation
A new tab has been added to the App Installer dialog to work around a known issue in the MSIX / Delivery Optimization subsystem:
App attach dialog additions
It is now possible to edit junction point.
Settings for app attach have now also an experimental switch to revert back to a legacy (MSIX Hero 1.5) way of app attach creation. There is also a configuration for default value of junction points.
Other changes
In the Packages list, it is now possible to filter applications by their updateability (with application installer) and to toggle between user/machine wide installations.
In the Events list, new filtering options have been added: time span, log source and the ability to filter verbose events.
The System page now shows sideloading and development features separately. Developer mode can be enabled with a toggle control.
In the Package Details view, the Files subsection now displays information about file and registry virtualization (for packages that support it).
In the Package Details view, the information displayed for applications now shows more relevant information for PWA and hosted applications.
Toolbars are now more responsive and collapse properly if there is not enough horizontal space.
MSIX Hero has been just updated to version 2.3.0. Make sure to have .NET 6.0 installed on your machine which is now required to start the program.
Command line package editing
Command line app msixherocli.exe has a new command which can be used for unattended editing of packages, especially for automation purposes.
The list of available operations is going to be extended in next releases, the following is currently supported:
Changing of package identity (name, publisher, version, processor architecture etc.) via msixherocli.exe edit <path> setIdentity ...
Setting properties like display names, publisher display name, logo etc. via msixherocli.exe edit <path> setProperties ...
Adding standard, restricted or custom capabilities via msixherocli.exe edit <path> addCapability ...
Setting build meta-data via msixherocli.exe edit <path> setBuildMetaData ...
Deleting files via msixherocli.exe edit <path> deleteFile ...
Adding or replacing files via msixherocli.exe edit <path> addFile ...
Setting registry keys via msixherocli.exe edit <path> setRegistryKey ...
Setting registry values via msixherocli.exe edit <path> setRegistryValue ...
Deleting registry keys via msixherocli.exe edit <path> deleteRegistryKey ...
Deleting registry values via msixherocli.exe edit <path> deleteRegistryValue ...
Importing registry keys from file or local registry via msixherocli.exe edit <path> importRegistry ...
These command may be executed in a single atomic operation via msixherocli.exe edit <path> list ..., where the list of commands is passed either via a file or command prompt.
Call msixherocli.exe edit <path> --help for extensive help for all options. The <path> in all above commands can be a manifest, MSIX or an unpacked package directory.
Support for dependencies in .appinstaller dialog
Appinstaller editor dialog now supports package dependencies.
Drop-down with timestamping authorities
Fields accepting timestamp URL have now a drop-down with suggested timestamping authorities
Dialog to calculate publisher hash, package name and Package Family Name
In a newly added dialog (accessible from the Dashboard) it is easy to calculate the required properties and understand how they are built.
Other improvements
Ability to filter package list by publisher hash or raw name/publisher.
Ability to skip the validation during packing (in both UI and command-line).
Ability to remove unpacked folder after packing it to MSIX file.
Ability to remove MSIX file after unpacking it to a folder (in both UI and command-line).

Updated MSIX/Windows SDK to 10.0.22000.0.
Microsoft Store availability
MSIX Hero is now available in Microsoft Store. Bear in mind, that due to certification processes, the updates from both Winget and Microsoft Store may be lagging a few days behind. Also, be aware that the Store release uses a different package name, and due to another application data directory it may not see the settings, configured by MSIX Hero installed from MSIX/.appinstaller/winget.
Download
The new version can be downloaded from the Download page or from the GitHub Releases page.
A new minor update is now available, it fixes a few visual glitches and improves the handling of build metadata when saving or signing MSIX packages.

New version of MSIX Hero is available. Below is the list of recent changes:
View directories, files, registry keys and values in your packages
Package properties have been redesigned to make space for two new tab: Files and Registry. They provide the overview of resources deployed by each package. For files, there is a button to show its content in a default editor.
This feature has been implemented for both installed packages and for compressed packages (MSIX) opened directly.
Winget Editor now supports v1 schema
Winget has moved on and has now more mature and feature-packed schema in version 1.0. MSIX Hero can now open and create files using the new schema (note: since the old schema has become obsolete, there is a little breaking change that the old formats cannot be opened or saved anymore).
New schema defines several new fields, which are now also supported directly from the GUI.
BTW: MSIX Hero support for Winget is not limited to MSIX – other setup types are also supported!
MSIX app attach – multiple files conversion + support for VHDX and CIM
MSIX app attach conversion dialog now supports multiple input files (similarly to how Package Signing handles them) and supports further output formats: VHDX and CIM (next to the already supported VHD). Note: Support for CIM is currently experimental.
New version of MSIX Hero is available. Below is the list of recent changes:
Support for Modification-, optional and related packages when generating .appinstaller files
Two new tabs are present in the App Installer editor: Optional packages and Related packages. These packages can be used to modify the base app (like modifying settings) or to extend functionality (like adding plugins).
Control the animation level
MSIX Hero 2.0 has introduced a new, rich UI, which however could cause issues on low-end machines, virtual machines or remote sessions. In this version, the amount of animations, transparency and other effects can be controlled in the UI. The default value Automatic ensures, that the program sets the most appropriate setting when launching the app.
New dashboard view
The dashboard has been cleaned-up, and shows a better overview of available actions.
Other changes
In case of errors when installing packages, the message shown in the UI is more precise.
It is now possible to add multiple files at once in the Sign Package dialog.
Minor UI changes and improvements.
Package selector now supports the .msixbundle extension.
Improved parsing of packages.
Resolved issues
Fixed an error shown when installing bundle packages
Fixed an issue in the App Installer editor, where the value of the Main Package URL was not saved properly.
Fixed the command line view generator in the app attach dialog, which was not including the --directory parameter.
Fixed a problem with the Add Folder prompt, which did not support cancelling.
Known issues
The format of winget manifests has changed recently. This build is not compatible with the new format yet. There is some work in a separate branch where the support is already covered, but there are some missing bits before it gets to the build (see issue Make winget editor compatible with v1 manifest format · Issue #110)
The new version can be downloaded from the Download page or from the GitHub Releases page.
The biggest change in this release (compared to previous version 2.0.46) is the overhaul of the Update Impact dialog, which received several new features and improvements:
Changes
Rewritten Update Impact analyzer
Added duplication and bar layout views
Added CLI support via updateImpact verb
Improved performance, especially for big packages
Ability to export to XML and start a new comparison
Added context menu item to open the Change Volume dialog for the selected package
Minor UI changes

Validation icons are consistent (tab items, input texts, dialogs, the settings view)
Tab items have now bigger padding
Added extra help with tooltip in the Modification Package section, checkbox Copy to VFS
Bug fixes
Fixed a problem with the partition drop-down, which was not showing any value in the Change Volume dialog
Fixed a problem with invisible text on Windows 10 with dark mode enabled
Fixed broken CLI verb dependencies
Fixed a problem with file overview in the Update impact dialog, which was not correct for packages having uncompressed Appx blocks (for example ZIP files)
Fixed a regression in Winget editor, where the dialog would crash with “Invalid filter” exception
Fixed a problem with Modification Package dialog, where the checkbox “Copy to VFS” was not reacting to changes of other controls
The new version can be downloaded from the Download page.
GitHub releases page contains technical release notes and compiled binaries. You can use Discussions or Issuesto report ideas and bugs. Also, contributions via pull request are welcome.
The builds available for the download on this page use the same codebase and build routines as the code from GitHub, with the only exception of digital signing for which the keys are not public.
New UI
After starting the app, the first and arguably the most visible change is the new UI. Classic ribbon has been deprecated in favor of a fresh and lightweight UI, which takes less screen space and thanks to the principles of Fluent Design better exposes available functions and places of interest.
The basic navigation patterns are the same – use the left menu with icons to change between Dashboard, Packages, Volumes, Events and System. Use the search bar to perform quick as-you-type filtering of the currently displayed list (if applicable). The most important options have dedicated buttons on the top bar, all functions can be also accessed from the context menu. You can toggle between USER and MACHINE packages by pressing the blue badge next to the search bar. Sorting, filtering and grouping is also available – to open the panel simply press the filter icon located over the package list.
Some less-frequently used options are available in drop-down menu, which can be access from the toggle button on the right.
By the way, several less-used menu items are now less prominently exposed, but still available by pressing the three dots menu on the right:
Dashboard
MSIX Hero 1.x had several useful tools for various purposes, but they were difficult to discover due to being effectively scattered over several places, ribbons and tabs. In this version, there is now a single place to see them:
Ability to start any entry point
In MSIX Hero 1.x it was possible to “start” an application. MSIX Hero would choose the most appropriate entry point and have it started. This might have been not quite what the user wanted in case of apps with many entry points. In version 2.0, things have been improved by the introduction of the new Start menu. To access it, select any app and click on the Start toggle button in the top action bar:
This menu consolidates several other menus from MSIX Hero 1.x. You have an option to pick any entry point (and the badge next to it shows the type of the app – whether it is a classic Win32 EXE, UWP or maybe even a Progressive Web App). The bottom part of the new menu shows the commands which can be executed in the package context. As always, you can customize the commands by visiting the Settings dialog.
Command-line generator
MSIX Hero has a command line interface which covers most of operations available through dialogs. In this build, some of dialogs support a new switch that shows the equivalent of the current settings with the use of silent command line interface. In the dialogs that already support this functionality, tick the following checkbox:
to reveal a command line textbox. You can continue to change the options and preferences, and the command line will be automatically recreated. For example, this is how signing command line can be automated:
If you prefer to first test the settings out, simply execute the action and wait for the confirmation screen to be shown. The command will be shown there:
Sorting and grouping by the installation date
In the main package list, MSIX Hero 2.0 displays installation dates instead of package architecture.
Additional sorting, filtering and grouping options have been added to change the view regarding each app’s installation date. To access the menu, locate the filter icon in the top right corner and press it to show all options:
New Event Viewer
The complete Event Viewer tab has been redesigned from scratch. It has now a common master-detail layout, and shows much more interesting information for each event. One benefit of using this list over a system viewer is that MSIX Hero extracts the names of affected packages, so that you can quickly locate events affecting particular products. Also in version 2.0, error codes (if any present) are extracted from the description and shown directly in the list:
Improved dependency analyzer
The dependency view uses now an improved algorithm, and due to several changes in captions and the new legend the relations are now much clearer.
Consolidated import and export of certificates from files
Actions like importing of a certificate file (.cer), trusting package publishers and exporting certificates from packages are now available from a single dialog (in MSIX Hero 1.x, these were available either separately or only from a command line). In this new dialog, the input file can be either a signed package or a certificate file – the choice of available actions depends on the input format. For example, when opening a signed package, the user can either extract the certificate or import it directly to the Trusted People store.
Other changes in 2.0
Improved performance and faster initial start.
Added toast notifications displayed after installing or removing an app.
It is possible to select the default screen that is opened when MSIX Hero starts (default is the Packages screen).
