Let me fix it myself

To disable Dr. Watson

  1. Click Start, click Run, type regedit.exe in the Open box, and then click OK.
  2. Locate and then click the following registry key:  
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AeDebug
    NOTE: Steps three and four are optional, However, they are necessary if you want to restore the default use of Dr. Watson. 
  3. Click the AeDebug key, and then click Export Registry File on the Registry menu.
  4. Type a name and location for the saved registry file, and then click  Save.
  5. Delete the AeDebug key.
Registry entries for debugger programs are located in the AeDebug key in Windows. The Dr. Watson program is installed by default in Windows, and is configured to run when an application error occurs (with a data value of 1 for the Auto value). The default values are as follows:
Value Name = Auto
Type = String (REG_SZ)
Data Value = 1 or 0. (Default is 1)

Value Name = Debugger
Type = String (REG_SZ)
Data Value = drwtsn32 -p %ld -e %ld -g

NOTE: This data value (drwtsn32 -p %ld -e %ld -g) is specific to Dr. Watson. Alternative debuggers will have their own values and parameters.

To enable Dr. Watson

  1. At a command prompt, type the following line, and then press ENTER:

    drwtsn32 -i
  2. Double-click the .reg file that you created in steps three and four that were discussed earlier.
