To install a msixbundle app on Windows 11, double-click the
msixbundle
file (or appxbundle, msix, and appx ) and click
Install.

If you come across issues, download and install the
App Installer
from the Microsoft Store and then try to install the
msixbundle
app. -
Another way to sideload apps, open PowerShell (admin) and run the
Add-AppxPackage -Path C:\Path\App-Package.msixbundle
command. This will also work for appxbundle, msix, or appx extensions.
Similar to the legacy exe file format, files in the msixbundle format on Windows 11 (and 10) are packages that developers generate with the MSIX Packing Tool and contain the application installation files.
The platform provides additional package kinds, such as appxbundle, msix, and appx, in addition to the msixbundle format. Although these packages describe separate bundles, they are similar. For example, several app packages are included in the msixbundle or appxbundle format to support several architectures, including ARM, x86, and x64. However, the application files for a particular architecture, such as x86 or x64, are contained in the msix or appx.
This is typically the preferred method for combining applications into a single package, which is subsequently sent to Microsoft for distribution via the Microsoft Store. But Windows 11 also allows you to use the App Installer or PowerShell to sideload the msixbundle, appxbundle, msix, and appx packages outside of the app store.
This tutorial will show you how to install an application on Windows 11 that uses the msixbundle format. You can also consult these Windows 10 instructions.

Install msixbundle apps on Windows 11
Use these procedures to install Windows 11 apps that are packed as msixbundle:
On Windows 11, open File Explorer.
Use the app package to open the folder location.
The msixbundle file (or appxbundle, msix, and appx) can be double-clicked.
On the Install button, click.
Click the “Launch” button (optional).
The Windows 11 software will install after you finish the steps.
To reinstall the software, you can alternatively start the installer.
The most recent version of the app installer is probably not installed on the computer if you are unable to use this procedure. The App Installer is available for download and installation via the Microsoft Store. If you are unable to install the app package, you might also need to enable Windows 11’s Developer Mode functionality.
Install msixbundle apps from PowerShell

For the actual path and name of the application bundle, which may have the msixbundle, appxbundle, msix, or appx extension, enter C:\Path\App-Package.msixbundle in the command.
The PowerShell command will start the app installation after you finish the steps.
