title: Excel dll for Microsoft.Office.Interop.Excel
body: <p>We want to use Microsoft.Office.Interop.Excel in our web application. Everything works fine on our local machines, but on our test machine we're running into problems. It has neither Visual Studio nor Office installed on it.<br>
  We're using .NET framework 2.0 and the server is running on Windows Server 2003 with IIS6.  </p>
  
  <p>Is there a dll that needs to be installed on the machine or added to the bin of the web application?</p>
