title: How to choose which Excel version is used for debugging a VSTO project with Visual Studio 2010
body: <p>I have developed an Excel add-in with Visual Studio 2010. When I debug my project, the add-in is loaded in Microsoft Excel 2010.
  Now I have also installed Office 2013 on my computer, and I'd like to use it for debugging my project, but Excel 2010 is still executed by default.</p>
  
  <p>Is there a way to choose which version of Excel is used for debugging a VSTO project in Visual Studio 2010? Or can I at least set Excel 2013 as the default program?</p>
