title: .NET Runtime version 2.0.50727.3082 - Fatal Execution Engine Error
body: <p>I found a couple posts regarding this error on StackOverflow and posts on various forums. There doesn't seem to be any one cause or solution for this error.</p>
  
  <p>So that it might help somebody else, below is the text of an email I sent to DevExpress regarding my experience with this error.</p>
  
  <p>===
  A month or two ago I installed an update to the CodeRush Express and the free Refactor products and it reset my Visual Studio settings.</p>
  
  <p>This week I installed the Silverlight developer tools. When I tried to install the RIA Services, it failed with an error that something was missing, I don't remember what it was. Given the prior problem when I updated the DevEx products, I decided to do a complete reinstall of Visual Studio. I uninstalled Visual Studio and all related products and reinstalled. Afterwards, whenever I opened a website in VS, VS would close and the following error message was entered in the event log: ".NET Runtime version 2.0.50727.3082 - Fatal Execution Engine Error (7A035FC0) (80131506)".</p>
  
  <p>Not finding a clear fix anywhere, I did another complete uninstall of Visual Studio and all related products, and started reinstalling and testing after each item. I installed everything else before the DevEx products: Visual Studio and SP1, the Silverlight 3 Tools, Expression Blend, Deep Zoom Composer, Silverlight 3 Toolkit and the RIA Services. After I installed CodeRush Express and Refactor! Free ASP.NET, everything was still working. After I installed Refactor! Free VB.NET, VS again started closing whenever a website was loaded and making the same event log entry.</p>
  
  <p>After I uninstalled Refactor VB.NET, the problem went away.</p>
  
  <p>The DevEx installs and the Microsoft Silverlight developer tools installs don't appear to be getting along together.</p>
