  <p>I completely removed VS2013, and tried to install the full application with update 4 included... i.e. from the complete 6GB install package.</p>

  Update 4 does not apply, or is blocked by another condition on your computer.</p>
  
  <p>Does anyone have any suggestions? The last few lines of the log file is:</p>
