title: Powershell ISE crash when loading
body: <p>I have encountered an error when trying to launch Powershell ISE. The launch starts with 'Loading' displayed in the splash panel, then a dialog box comes up with "An unexpected error has occurred, and Windows PowerShell ISE must close"
  I have Googled this error and come up with nothing specific, but I have followed a few steps that have been suggested for fixing other issues.</p>
  
  <pre><code>Platform: Windows 8.1 Pro
  
  Powershell ISE product version: 10.0.14409.1005 
  
  (Cannot open shell so cannot run cmdlet to get exect version details)
  </code></pre>
  
  <p>Things I have tried</p>
  
  <pre><code>1 The plain Powershell shell **does** launch.    
  2 Tried launching ISE with -NoProfile &amp; -MTA switches no luck    
  3 Rename powershel_ise.exe.config so it cannot be read in both System32 &amp; WOW64 folders    
  4 Upgrade .NET Framework to 4.5.1    
  5 Upgrade Management Framework to 5.1    
  6 Other machines within our environment with same image and patch level have **not** encountered this problem    
  7 Cannot find an associated error in the Event viewer logs
  </code></pre>
  
  <p>I really don't want to blow the machine away and start again so any suggestions or fix would be appreciated !</p>
