title: What does "Wrap the file in another setup package through Visual Studio or other Windows Installer aware setup editor" mean?
body: <p>I am working in Visual Studio 2012 and I was missing the "Microsoft.Office.Interop.Excel" assembly. After downloading the missing exe from <a href="http://www.microsoft.com/en-us/download/details.aspx?id=3508" rel="nofollow">http://www.microsoft.com/en-us/download/details.aspx?id=3508</a>,<br>
  the instructions are as follows:<br>
  "Wrap the O2010pia.msi file in another setup package through Visual Studio or other Windows Installer aware setup editor"<br>
  I ran the exe, but the missing assembly is still missing from Visual Studio.
  I am quite new to development and after googling for a while, I am no closer to understanding what this means. I would greatly appreciate some insight. </p>
