How to Install Appx and AppxBundle Files on Windows 10 and Windows 11

Appx and AppxBundle files are application packages used to install apps on Windows 10 and Windows 11 outside of the Microsoft Store. These formats allow manual installation, which can be helpful if an app is unavailable in the store or if you want to install custom applications.

Preparing to Install Appx and AppxBundle Files

Before starting, make sure your device allows app installation from external sources:

  1. Open Settings (Win + I), go to Apps > Apps & features.
  2. Locate the Installing apps option and select Allow apps from any source, if available.

Method 1: Installation via PowerShell

One of the simplest and most flexible ways to install Appx and AppxBundle files is by using PowerShell. Follow these steps:

  1. Download the .appx or .appxbundle file and save it to a convenient location on your drive.
  2. Open PowerShell as an administrator. To do this, press Win + X and select Windows PowerShell (Admin).
  3. Enter the following command to install the package:
Add-AppxPackage -Path "C:\path\to\your\file.appx"

Replace C:\path\to\your\file.appx with the full path to your file. After running the command, PowerShell will install the application.

Method 2: Installation via App Installer

Windows 10 and 11 also have a built-in App Installer that simplifies the installation process:

  1. Double-click on the .appx or .appxbundle file.
  2. In the App Installer window, click Install.
  3. After the installation completes, you’ll see a notification, and the app will appear in the Start menu.

Method 3: Installation via Microsoft Store (if a link is available)

Sometimes, apps provide an installation link through the Microsoft Store, making installation straightforward:

  1. Open the Microsoft Store and paste the link to the app.
  2. Click Get or Install.

Possible Errors and Solutions

You might encounter some errors while installing Appx or AppxBundle files. Here are a few common ones:
