title: Microsoft.Interop.Excel with Visual Studio 2012 no longer working
body: <p>I was using a DLL from a coworker and wanted to merge their project into a single solution for maintainability reasons.  Their DLL reads data rows out of an Excel sheet, my application takes the data and displays it in a listview control. The coworker developed their part in Visual Studio 2008, while my application was developed in Visual Studio 2012.  All of the code is written in C#.  </p>
  
  <p>After merging the project, I had to update the reference of Microsoft.Interop.Excel to the 14.0 object library in VS2012.  When I test using the updated solution on my machine, everything works just great - the Excel file is read and everything looks good; however, when I run it on a test machine, the application no longer works.  It does not appear to read the data out of the Excel sheet. </p>
  
  <p>My machine is running Office 2013, while the other machines are running Office 2010.  I tried it on another machine running Office 2010 and VS2012 and no problems.  I also tried downloading the MS redistributables, but did not have any luck. </p>
  
  <p>Has anyone had similar issues?</p>
