title: How to redistribute Visual Studio 2010 Tools for Office Runtime with InstallShield correctly?
body: <p>Using: VS 2012,
  InstallShield 2012 Spring Express</p>
  
  <p>For my Excel Add-In I need to redistribute to prerequisites:
  - Microsoft .NET Framework 4.5 Full
  - Visual Studio 2010 Tools for Office Runtime</p>
  
  <p>There is no problem with .NET Framework in any case. I redistribute it by setup or by web download. Everything is OK.</p>
  
  <p>But with VSTO I've got some troubles:
  1) "web download" is not working properly. Even if I use this recommendations - <a href="http://msdn.microsoft.com/en-us/library/vstudio/cc442767.aspx#Configure" rel="nofollow">http://msdn.microsoft.com/en-us/library/vstudio/cc442767.aspx#Configure</a></p>
  
  <p>After all, I downloaded vstor_redist.exe (~40 Mb) and added it to setup.
  2) The setup starts to install vstor_redist.exe and really does it! But then I see a strange InstallShield message that VSTO installation appears to have failed.
  Nevertheless after installation the application works correctly.</p>
  
  <p>Two questions:
  How to redistribute VSTO with web download option?
  How to avoid the appearance of useless "installation failed message"?
  It seems these are InstallShield bugs...</p>
