QtIFW on Windows: how to invoke uninstaller if user tries to uninstall app

Question

On Windows, if you right-click > Uninstall an app, by default it opens the Settings app on Apps > Installed Apps. However for many apps, it will start a custom uninstaller instead.

For an app installed using the Qt Installer Framework (QtIFW) you also get an installer (e.g. MaintenanceTool.exe). This can be executed in uninstaller mode using the --start-uninstaller command line option.

How do I link the two?

In other words, if a user tries to directly uninstall my app, I want it to invoke C:\Program Files\MyApp\MaintenanceTool.exe --start-uninstaller.

Thanks @glennr I didn't realise it was supposed to be part of the functionality. Good to know. I've added a vote FWIW and I'll sit tight. — Paul Masri-Stone

Add your registry info here. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\MaintenanceTool (The name is optional.)

You'll need to provide: UninstallString (Your command for uninstallation, if I'm correct.) InstallLocation (The folder or directory where the person installed their app.)

I don't really have a lot of experience on this kind of thing, so I assume this is the correct answer based on my knowledge.
