title: Microsoft JScript runtime error when using "Use Local IIS Web Server"
body: <p>Everything was working fine until someone in a Microsoft forum had try a couple devenv switches in command prompt mode: devenv /Resetsettings and Run devenv /ResetSkipPkgs.Prompt for an unrelated problem, namely that I could not save aspx files with one click of the save button.  Ever since then, I am running into a new problem.</p>
  
  <p>I tried uninstalling VS2012, rebooting, and reinstalling to no avail.</p>
  
  <p>The problem is that I receive a Microsoft JScript runtime error when using the "Use Local IIS Web Server" setting.  IIS cannot find variables defined in files it loaded.  When I run with the "Use Visual Studio Development Server" option, then it works.</p>
  
  <p>Why is that and how can I get the "Use Local IIS Web Server" working again.</p>
  
  <p>2 images showing the problem.

  <p>(I uploaded the images yesterday, not sure what happened.)</p>
  
  <p>I am not sure what to make of the problem.  I saw another post on a different forum regarding a similar issue.</p>
