How to install a Windows 8 App Without Submitting to Store [closed]

For a customer I need a to present our Windows 8 Metro App. When I deploy my solution or project, I get a exe but I can't install it. I get a MessageError, that I can only start the exe in a app container.

How can I create a version of my application to give it to my customer without loading it up to the Microsoft Store?

Is Windows 8.1 store closed?

It is shut down for Windows 8. Beginning in July 2019, the Windows 8 Store is officially closed. While you can no longer install or update applications from the Windows 8 Store, you can continue using those already installed.

Does Microsoft Store still work on Windows 8?

When you're connected to the Internet, Windows 8.1 clients obtain updates to Microsoft Store apps directly from the Microsoft Store app. The Microsoft Store app is visible on the Windows Start screen.

Use the PowerShell cmdlet add-appxpackage. For example:

add-appxpackage C:\myapp.appx
