title: c# interop excel worksheet visible during run only on windows 7
body: <p>I have created a C# Winforms app and on Windows 7, as I populate my excel sheet (via Microsoft Outlook 15.0 Object Library), the sheet opens and you can see it being populated, and then it closes as I programmatically close the object. I do not what the excel sheet to appear as it's being populated. </p>
  
  <p>The excel sheet does not appear when I run it in visual studio on my windows 2008 server. It only appears on Windows 7 (64 bit). I've tried the following (and here is my code to create the objects. I have excel 2013 64-bit on the Windows 7 (where the sheet shows) box and the server(where the excel sheet does not show).
