C# Explicity throw an error on Process.Start()
<p>I'm a C# beginner and I have made a little launcher for a game and to start it, I'm using this button event:</p>

<pre><code>private void button5_MouseClick(object sender, MouseEventArgs e)
    {
        Process.Start("engine.exe", "/load /config debug");
        Application.Exit();
    }
</code></pre>

<p>As you can see this also uses Application.Exit() to close the launcher when the game starts, because they are separate.</p>

<p>What I want to know is if my method is good to start the game + close launcher and also, </p>

<p>I would like to know how to make a pop up message saying "Engine.exe not found" when I'm clicking the button and engine.exe is missing.</p>

<p>Thanks!</p>
