In the past few days, when I tried run my picture management software, I got an error message saying that my debugger don't have the just-in-time debugging function. Also, sometimes opening a MSDN url would cause the same thing, like this one: http://msdn.microsoft.com/en-us/lib... I use google to find the solution and some suggest the "Debugging Tools for Windows (x86)" frome MS. I installed the program and tried my picture management software, the debug software jump out and display the following message: Microsoft (R) Windows Debugger Version 6.9.0003.113 X86 Copyright (c) Microsoft Corporation.

PS: Before I got the just-in-time debugging error, I didn't install anything. The just-in-time debugging error just pop out for no reason. PS2: The picture management software is call WinCV, created by a Chinese programmer. I have used this program over 6 year and never have any problem with it. Hello!

I suggest that you contact tech support for the application that is failing.

I got this error a couple of weeks ago on a machine when trying to run a database. The only way I could get round it was to go into users/groups and add the user to the Debugger Users group. The machine kept trying to debug the program but because the user was not a debugger user it just kept crashing out. After I added the user the machine ran as normal. Not sure if this is the same sort of problem you are having but wont hurt to try. hth scott Unknown has caused an error in unknown and unknown needs to restart.
