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.
