How do I disable the 'Debug / Close Application' dialog on Windows Vista?

Windows Testing Windows Vista Crash Reports Windows Error-Reporting

Windows Problem Overview

When an application crashes on Windows and a debugger such as Visual Studio is installed the following modal dialog appears:

> [Title: Microsoft Windows] > > X has stopped working > > A problem caused the program to stop > working correctly. Windows will close > the program and notify you if a > solution is available. > > [Debug][Close Application]

Is there a way to disable this dialog? That is, have the program just crash and burn silently?

My scenario is that I would like to run several automated tests, some of which will crash due to bugs in the application under test. I don't want these dialogs stalling the automation run.

Searching around I think I've located the solution for disabling this on Windows XP, which is nuking this reg key:

> HKLM\Software\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger

However, that did not work on Windows Vista.

Solution 1 - Windows

To force Windows Error Reporting (WER) to take a crash dump and close the app, instead of prompting you to debug the program, you can set these registry entries:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting]
"ForceQueue"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\Consent]
"DefaultConsent"=dword:00000001

After this is set, when your apps crash, you should see *.hdmp and *.mdmp files in:

%ALLUSERSPROFILE%\Microsoft\Windows\WER\

Solution 2 - Windows

See here:

http://msdn.microsoft.com/en-us/library/bb513638.aspx

regedit

DWORD HKLM or HKCU\Software\Microsoft\Windows\Windows Error Reporting\DontShowUI = "1"

will make WER silently report. Then you can set

DWORD HKLM or HKCU\Software\Microsoft\Windows\Windows Error Reporting\Disabled = "1"

to stop it from talking to MS.

I'm not sure if this refers to exactly the same dialog but here is an alternative approach from Raymond Chen:

DWORD dwMode = SetErrorMode(SEM_NOGPFAULTERRORBOX);
SetErrorMode(dwMode | SEM_NOGPFAULTERRORBOX);

Solution 4 - Windows

I had to disable this for release automation work on Windows 64-bits for Firefox and I did the following:

gpedit.msc
Computer configuration -> Administrative Templates
Windows Components -> Windows Error Reporting
Set "Prevent display of the user interface for critical errors" to Enabled

It is similar what was accomplished for Customer Experience reporting in: http://www.blogsdna.com/2137/fix-windows-installer-explorer-update-has-stopped-working-in-windows-7.htm

Solution 5 - Windows

In my context, I only want to suppress the popup for my unit tests and not for the entire system. I've found that a combination of functions are needed in order to suppress these errors, such as catching unhandled exceptions, suppressing run time checks (such as the validity of the stack pointer) and the error mode flags. This is what I've used with some success:

#include <windows.h>
#include <rtcapi.h>
int exception_handler(LPEXCEPTION_POINTERS p)
{
    printf("Exception detected during the unit tests!\n");
    exit(1);
}
int runtime_check_handler(int errorType, const char *filename, int linenumber, const char *moduleName, const char *format, ...)
{
    printf("Error type %d at %s line %d in %s", errorType, filename, linenumber, moduleName);
    exit(1);
}

int main()
{
    DWORD dwMode = SetErrorMode(SEM_NOGPFAULTERRORBOX);
    SetErrorMode(dwMode | SEM_NOGPFAULTERRORBOX);
    SetUnhandledExceptionFilter((LPTOP_LEVEL_EXCEPTION_FILTER)&exception_handler); 
    _RTC_SetErrorFunc(&runtime_check_handler);
    
    // Run your tests here
    
    return 0;
}

Solution 6 - Windows

In WPF application

[DllImport("kernel32.dll", SetLastError = true)]
static extern int SetErrorMode(int wMode);

[DllImport("kernel32.dll")]
static extern FilterDelegate SetUnhandledExceptionFilter(FilterDelegate lpTopLevelExceptionFilter);
public delegate bool FilterDelegate(Exception ex);

public static void DisableChashReport()
{
 FilterDelegate fd = delegate(Exception ex)
 {
  return true;
 };
 SetUnhandledExceptionFilter(fd);
 SetErrorMode(SetErrorMode(0) | 0x0002 );
}

Solution 7 - Windows

You have to implement an unhandled exception filter which simply quits your application, then set that filter function with SetUnhandledExceptionFilter().

If you're using the secure CRT, you also have to provide your own invalid parameter handler and set this with _set_invalid_parameter_handler().

This blog post has some information too: http://blog.kalmbachnet.de/?postid=75

Solution 8 - Windows

During test you can run with a 'debugger' like ADPlus attached which can be configured in many useful ways to collect data (minidumps) on errors and yet prevent the modal dialog problems you state above.

If you want to get some useful information when your app crashes in production you can configure Microsoft Error reporting to get something similar to ADPlus data.

Solution 9 - Windows

This isn't a direct answer to the question since this is a workaround and the question is about how to disable that feature, but in my case, I'm a user on a server with limited permissions and cannot disable the feature using one of the other answers. So, I needed a workaround. This will likely work for at least some others who end up on this question.

I used autohotkey portable and created a macro that once a minute checks to see if the popup box exists, and if it does, clicks the button to close the program. In my case, that's sufficient, and leaves the feature on for other users. It requires that I start the script when I run the at-risk program, but it works for my needs.

The script is as follows:

sleep_duration = 60000 ; how often to check, in milliseconds.
                       ; 60000 is a full minute

Loop
{
	IfWinExist, ahk_class #32770 ; use autohotkey's window spy to confirm that
                ; ahk_class #32770 is it for you. This seemed to be consistent
                ; across all errors like this on Windows Server 2008
	{
		ControlClick, Button2, ahk_class #32770 ; sends the click.
                ; Button2 is the control name and then the following
                ; is that window name again
	}
	Sleep, sleep_duration ; wait for the time set above
}

edit: A quick flag. When other things are up, this seems to attempt to activate controls in the foreground window - it's supposed to send it to the program in the background. If I find a fix, I'll edit this answer to reflect it, but for now, be cautious about using this and trying to do other work on a machine at the same time.

After trying everything else on the internet to get rid of just in time debugger, I found a simple way that actually worked and I hope will help someone else.

Go to Control Panel Go to Administrative Tools Go to Services Look down the list for Machine Debug Manager Right Click on it and click on Properties Under the General Tab, look for Start Up Type Click on Disable. Click on Apply and OK.

I haven't seen the debugger message since, and my computer is running perfectly.

Instead of changing values in the registry you can completly disable the error reporting on Windows Server 2008 R2, Windows Server 2012 and Windows 8 with: serverWerOptin /disable
