title: Unable to load DLL 'Microsoft.Expression.WindowsXamlInterop.dll
body: <p>I'm running VisualStudio 2013 Ultimate (with Blend) on 2 separate machines (different vendors) and have the same issue.</p>
  
  <p>When I double click on to the MainPage.Xaml when creating new windows store app or phone app the designer does not open.</p>
  
  <p>I receive the following error:</p>
  
  <blockquote>
    <p>System.DllNotFoundException Unable to load DLL
    'Microsoft.Expression.WindowsXamlInterop.dll': The specified module
    could not be found. (Exception from HRESULT: 0x8007007E</p>
  </blockquote>
  
  <p>This occurs on VS update 2, 3 &amp; 4 RC. I have tried repairing VS and the .net framework. I've tried installing 4.5.2. I have deleted the contents in the ShadowCache directory but still no cigar.</p>
  
  <p>This issue is driving me crazy. This didn't happen prior to VS update 2...which I need for some XAML development.</p>
  
  <p>Any ideas?</p>
  
  <p>Many Thanks</p>
