title: Unrecoverable build error - whilst trying to build setup on VS2015
body: <p>My build fails every time when I try and build my setup project.  The error in the output window is just:</p>
  
  <p><strong>ERROR: Unrecoverable build error</strong></p>
  
  <p>What I have tried already</p>
  
  <ul>
  <li>Restarting my computer and Visual Studio</li>
  <li>Registering ole32.dll</li>
  <li>Clean and rebuild all</li>
  <li>Deleting bin and obj folders</li>
  <li>Removing temporary files with VS in the name in \AppData\LocalTemp</li>
  <li>Running Visual Studio as an administrator</li>
  <li>Pausing the real time protection on my antivirus</li>
  <li>Deleting the temporary file that the setup build leaves in there.</li>
  <li>Running the process monitor during the build.</li>
  <li>Checking if my project contains duplicate folder names (it does not).</li>
  </ul>
  
  <p>Note:
  Similar question but not the same as it is for a much earlier version of Visual Studio:</p>
