If you are trying to sideload an app on Windows 11 and you encounter the error “Deployment failed with HRESULT: 0x80073CFB“, here are some possible solutions you can try:

1. Make sure Developer Mode is enabled:

Before you can sideload apps on Windows 11, you need to enable Developer Mode. To do this, go to Settings > Update & Security > For developers, and select “Developer mode“. If Developer Mode is not enabled, you will not be able to sideload apps.

2. Check the app package for errors:

If the app package is corrupted or contains errors, you may encounter this error. Make sure the app package is not corrupted and that it contains all the necessary files and metadata.

3. Disable Windows Defender Antivirus:

Windows Defender Antivirus may sometimes interfere with app installations, including sideloading. Try disabling Windows Defender temporarily and see if the error goes away. To do this, go to Settings > Update & Security > Windows Security > Virus & threat protection, and turn off “Real-time protection“.

4. Use PowerShell to install the app package:

If you are still encountering the error, you can try using PowerShell to install the app package. Open PowerShell as an administrator, navigate to the directory where the app package is located, and run the following command:

Add-AppxPackage -Path [path to app package]

This should install the app package without encountering the error.

If none of these solutions work, you may need to contact the app developer or Microsoft support for further assistance.
