Visual Studio 2013 crashes at startup because of CLR runtime settings

This issue may occur after you make changes to the DevEnv.Exe.Config (or its express equivalent) file. The changes are unsupported and can introduce instabilities into Visual Studio. Therefore, you should not make any changes to the configuration files unless directed by a Microsoft support engineer to do this.


To resolve this issue, remove the entries that you changed from the configuration file. For example, you can remove the common language runtime (CLR) setting entry NetFx40_LegacySecurityPolicy which is known to crash Microsoft Visual Studio 2013 in the configuration file.

Note You can find the configuration files (<App Id>.exe.config) under the following folders:
  • %PROGRAMFILES%\Microsoft Visual Studio 12.0\Common7\IDE
  • %ProgramFiles(x86)%\Microsoft Visual Studio 12.0\Common7\IDE
  • %LOCALAPPDATA%\Microsoft\VisualStudio\12.0


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
