title: Visual Studio project with references on another system
body: <p>My employer had me program a specific program in VB. Net.
  I finished it, and it works perfectly on my system. The problem is the following: He wants to be able to edit said program code on his PC, transferring it was simple.. Now (on his pc) the code is full of error signs because the references (Microsoft Word &amp; Excel Project Libraries) can't be selected. It simply doesn't let him select the references because "a reference is already there, you have to delete "Microsoft.Office.Interop.Word" before adding the new reference" (loosely translated from German). I suspect the problem might be because I use Office 2016 while he used the 2010 version. Even so, how can I pull this off? Thanks in advance for your answers.</p>
