Note

This article applies to Visual Studio 2015. If you're looking for the latest Visual Studio documentation, see Visual Studio documentation. We recommend upgrading to the latest version of Visual Studio. Download it here

To access the Just-In-Time page, go to the Tools menu and click Options. In the Options dialog box, expand the Debugging node and select Just-In-Time. This page allows you to enable Just-In-Time debugging for managed code, native code, and script. For more information, see Just-In-Time Debugging.

You can enable Just-In-Time debugging for these program types:

  • Managed

  • Native

  • Script

    Just-In-Time debugging is a technique for debugging a program that is started outside Visual Studio. You can run a program created in Visual Studio outside of the Visual Studio environment. If you have enabled Just-in-time debugging, a crash will display a dialog box that asks if you want to debug.

Associated Warnings

When you visit this page of the Options dialog box, you might see a warning message like this:

Another debugger has registered itself as the Just-In-Time debugger. To repair, enable Just-In-Time debugging or run Visual Studio repair.

This message occurs if you have another debugger, possibly an older version of Visual Studio debugger, set as the Just-In-Time debugger.

Another message that you might see is as follows:

Just-In-Time debugging registration errors detected. To repair, enable Just-In-Time debugging or run Visual Studio repair.

If you see either of these warnings, Just-In-Time debugging with Visual Studio 2012 requires Administrator privileges until you have fixed the problem. If you try to enable just-as a non-administrator under these conditions, you will see the following error message:

Access is denied. Have an administrator enable Just-In-Time debugging, or repair your installation of Visual Studio.
