Just-In-Time, Debugging, Options Dialog Box

When you work with the Just-In-Time debugger in Visual Studio, configuration options for the debugger are accessible from the Tools > Options or Debug > Options menu.

Open the Tools (or Debug) > Options pane, expand the All Settings > Debugging > General section, and select the Configure Just-In-Time debugging link. Configure the options in the Visual Studio Debugger Options dialog. You can enable Just-In-Time debugging for managed code and native code.

Just-In-Time debugging is a technique for debugging a program started outside Visual Studio. You can run a program created in Visual Studio outside of the Visual Studio environment. If you enable Just-in-time debugging, you see a crash dialog that asks if you want to debug the program. For more information, see Just-In-Time Debugging.

Associated warnings

When you work with the Just-In-Time debugger, 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 requires Administrator privileges until you resolve the problem. If you try to enable the feature as a nonadministrator under these conditions, you see the following error message:

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