 How to Fix “Dr.Watson Postmortem Debugger has encountered a Problem and needs to Close”If you are using Internet Explorer, Outlook or any Application, you can get Dr .Watson Postmortem Debugger error. You can also observe drwtsn32.exe process running in the task manager. Dr.Watson crashes when other applications crashed.

What’s Dr.Watson? Is this a Virus?

Dr.Watson for Windows is a debugger that will be useful to debug and creates log files when a error occurs with in a program. Technical support people will analyze these log files and fix the errors. It is not a virus or a malware program. Dr.Watson creates log files at  C:\Documents and Settings\All Users\Application Data\Microsoft\Dr Watson.

 How to Fix “Dr.Watson Postmortem Debugger has encountered a Problem and needs to Close”

It actually crashes some times frequently and gives the error as given below.

Dr.Watson Postmortem Debugger has encountered a problems and needs to close

Why Dr.Watson crashes and give error?

Unfortunately, when you are browsing through Internet Explorer or working with any other program if that program crashes, then Dr.Watson program it self crashes and gives that error.

Does I really need this Dr.Watson  program?

No not really in fact Windows Error Reporting service also do the same as Dr.Watson, as you know you can send error reports to Microsoft through Windows Error  Reporting also.

What’s the Fix?

Fix to this problem is disabling Dr.Watson as we have alternative Windows Error Reporting available, we don’t require Dr.Watson.

Disabling Dr.Watson

1.Click Start>Run>type Regedit and click ok.

2.Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current Version

3.Select AeDebug in the right pane, double click it and enter value 0.

4.Close registry editor, restart your computer.

You won’t get this error again in future.

If you have problem with access to registry, download the registry file released by Microsoft, run that registry file.

I have the same problem that Eric posted on April 24, 2009. Like Eric said, any ideas?

I seemed to be able to disable Dr. Watson ok however now I get a window that says
Explorer.EXE-Application Error
The instruction at "series of numbers/letters"referenced memory at "series of numbers/letters". The memory could not be "read".
Click OK to terminate program

Then when I click OK I get
Runtime error 216 at series of numbers/letters

I can only close this by going to task manager and when I do the first window pops up again so I'm stuck. Each time the numbers and letters are different.
The only way I can run is in safe mode.
Any ideas


Andrea November 16, 2009 at 7:08 am

I have this issue as well. When I turn on my laptop, I get the explorer error first. I click dont send and then the Dr Watson error. I have any additional issue that I do not have anything that shows up in my taskbar. No Start button, no taskbar icons, no clock. After these error messages are gone I cannot click on any of the program icons on the desktop. My only option seems to be is using task manager. If I go to File, then New Task (run) then browse, all I get is locked up with the hour glass and then my task manager is not responding so I have to shut it down. Any thoughts on this mess? lol Thanks!


Anonymous December 3, 2009 at 2:55 am

I am having the same problem as Andrea is there any solution on how to fix this?


Jack Creason March 4, 2010 at 10:37 am

When my computer boots up the DrWatson Postmortem Debugger has encountered an error box pops up. I can send the report, but the box reappears. I can't click on the start menu or even tab away to use the keyboard. I've crtl-alt-del, but the same thing happens. I've also done the system restore to no avail.

How can I fix this, if I can't do anything?

Dr. Watson is a debugger and it triggers when an eror occurs in some program. Turning off the debugger or disabling it is not the solution. If it is disabled, it won’t inform you that the error has occured…we should be able to know solve the problem that is encountered by Dr. Watson debugger…someone please comment


Venkat May 15, 2010 at 4:20 pm

Hey Umar just read the full article and comment , as u said it will crash when other application crashes, we have already Windows Error reporting service available which reports for errors make sure you enabled that service and disabling Dr.Watson will help this way.Dr.watson has nothing to do it is also jsut like Windows Error reporting service.


Duncan June 12, 2010 at 8:29 am

Where do this Dr. Watson thing come from?How did it get into my computer?


Venkat June 12, 2010 at 1:20 pm

Duncan it will comes along with Windows like Windows Error reporting, disabling Dr.Watson does no harm to your Computer.Windows error reporting service will alert you when critical errors do occur.


sKatti July 7, 2010 at 5:15 pm

We noticed that the Windows debugger program, Dr. Watson, seems to be configured differently between XP 32 & 64 bit. I believe that Dr. Watson popped up when a user experienced an Alias issue. This only happened on 32 bit. On 64 bit the same error was experienced but Dr. Watson did not popup. Can someone help us understand why Dr. Watson would behave differently on 32 & 64 bit systems?


Venkat July 7, 2010 at 6:25 pm

Will let you know If I know about it ,since most users use 32-bit systems including me too.


Bridget September 8, 2010 at 1:10 pm

When i go to run and regedit there is no title on the right hand side as mentioned. My debugger thing only comes up when i am trying to print something?

Hi sir, I have a problem with DrWatson popping up every now and then. I tried running ‘regedit’ through ‘Run’, but nothing happens. The task manager also does not open. I downloaded the ‘Fix It’ file and tried to run it, but it doesnt open and the same DrWatson error appears.. I can hardly do anything. I opened ‘drwtson32′ through ‘Run’ and unchecked all the boxes… Still the error persists. Please help.


Venkat eswarlu September 4, 2013 at 7:23 am

First make sure you can able to open Registry Editor and Task Manager,if you can’t try the below links then I suggest you to use registry file or fix it.


rook March 22, 2014 at 9:07 am

Thanks to venkat. I have fixed the problem and error didn’t come.
