The most common reason for this is a missing or damaged APPX file. Other possible causes include not having the right permissions or not running PowerShell as an administrator. This guide will walk you through several solutions to fix the “Add-AppxPackage Deployment failed with HRESULT” error.
1. Restart Your Computer
If you get an error in Windows PowerShell, simply restarting your computer can often solve the problem. Restarting ensures all system processes and services start fresh, which may quickly resolve the error.
2. Run the Windows Store Troubleshooter
Windows includes a built-in troubleshooting tool that can automatically find and fix problems with Microsoft Store apps. Running the troubleshooter is a good first step to detect and resolve issues causing errors like this one.
3. Disable the StartMenuExperienceHost EXE Process
The StartMenuExperienceHost.exe process helps manage the Windows Start Menu, but it can sometimes interfere with PowerShell commands. Disabling it temporarily before running your PowerShell command may solve the problem.
4. Run System File Scans
Corrupted system files are a common reason for this error. These files can block some actions from running correctly in your system. Running a system file scan will help find and repair any damaged files.
5. Update Your Windows
An outdated version of Windows might prevent some programs or updates from working properly and can contribute to these errors. Keeping Windows up to date is essential.
6. Run Windows in Safe Mode
If you’re still facing the error, try starting Windows in Safe Mode. In Safe Mode, your computer starts with a basic set of drivers and programs, which can help isolate what’s causing the problem.
7. Use an In-Place Upgrade
An In-Place Upgrade lets you repair Windows without deleting your personal files or apps. Use this only as a last resort if everything else fails.
