As you've observed, Windows Explorer will try to launch a new instance of your app when you double-click a file associated with your application. You can't change that. What you can do is have the new instance check whether an instance is already running and, if so, tell the running instance to load the file. There are lots of ways to establish this sort of communication. You could listen on a port, periodically check for a file in a particular location, etc. How to do it is up to you.
