title: Xamarin Android Player unable to find VirtualBox - How do I fix it?
body: <p>I have created a Windows Phone 7 app using XNA 4.0 that I now want to port over to Android MonoGame. I am currently using a trial edition of Xamarin Business and I want to use an emulator to test the game as I do not currently have access to a physical Android phone. I have downloaded both Xamarin Android Player and Oracle VM VirtualBox 5.0.4 (I think that's the version I've installed, at least). When I open Xamarin Android Player, I'm just presented with the message:</p>
  
  <pre><code>Unable to find VirtualBox
  
  Error when attempting to find VirtualBox please check it's installed and try again.
  
  Xamarin Android Player will now exit.
  </code></pre>
  
  <p>No version of Visual Studio or VirtualBox is open and running when I'm opening Android Player. Does anyone know how to fix this issue so that I can the emulator running and test the MonoGame version of the app?</p>
