title: Is there a tool that will combine a 32 bit + 64 bit application and pack them together in one 32+64 bit application
body: <p>In Windows 2008 R2 server (server core installation) <a href="http://msdn.microsoft.com/en-us/library/dd371790%28v=VS.85%29.aspx" rel="nofollow">wow64 is no longer a required component</a>.</p>
  
  <p>I can compile a 32 bit application using the same source code as a 64 bit application (with a few ifdefs here and there). </p>
  
  <p>Is there a tool that puts both versions of my app in one executable so that my 32+64 bit application will run on a pure 32-bit Windows <strong>and</strong> a 64-bit only Windows?</p>
  
  <p><em>Note that I am not talking about a packer because the packer itself will be either 32 or 64 bit.</em>  </p>
