title: InstallSheild build error 6109
body: <p>I'm using InstallShield (LE) project in VS2013 Update 5 to create an installer package for a number of windows services and a web site. However, every now and again, after updating Nugget packages, the installer project breaks upon build with the following error:</p>
  
  <p>Error   16  -6109: Internal build error ISEXP : error : -6109: Internal build error</p>
  
  <p>The EventLog in Windows doesn't show anything and the log generated by the installer project also doesn't describe the error further.</p>
  
  <p>I've tried "Cleaning" the solution and "Rebuilding", but nothing helps. I've tried deleting to *.suo file for the solution, which helped a few times (but now this doesn't work anymore).</p>
  
  <p>It should be noted that the services and the web site all work as expected.</p>
  
  <p>Any help is much appreciated...</p>
