C Runtime Error R6033

  • Article

Attempt to use MSIL code from this assembly during native code initialization. This indicates a bug in your application. It is most likely the result of calling an MSIL-compiled (/clr) function from a native constructor or from DllMain.

Note

If you encounter this error message while running an app, the app was shut down because it has an internal problem. This error can be caused by a bug in the app, or by a bug in an add-in or extension that it uses.

You can try these steps to fix this error:

  • Use the Apps and Features or Programs and Features page in the Control Panel to repair or reinstall the program.
  • Use the Apps and Features or Programs and Features page in the Control Panel to remove, repair or reinstall any extensions or add-ins.
  • Check Windows Update in the Control Panel for software updates.
  • Check for an updated version of the app. Contact the app vendor if the problem persists.

Information for Programmers

This diagnostic indicates that MSIL instructions were executing during loader lock. This can occur if you have compiled native C++ by using the /clr flag. Only use the /clr flag on modules that contain managed code. For more information, see Initialization of Mixed Assemblies.
