Disable 32-bit Program User Mode Exception Error Messages

To disable 32-bit program User mode exception error messages:

1. Register Dr. Watson as your default 32-bit program debugger. To do so:
   1. Open a command prompt, type the following text, and then press ENTER:

      CD %SystemRoot%\SysWow64

   2. From the Syswow64 folder, type the following text, and then press ENTER:

      drwtsn32 -i

      NOTE:You must be in the SysWow64 folder when you register Dr. Watson as your program debugger. You cannot disable 32-bit exceptions if you register the 64-bit version of Dr. Watson.
2. Click Start, click Run, type the following text, and then press ENTER:

   %SystemRoot%\syswow64\drwtsn32

3. Click to clear the Visual Notification check box, and then click OK.
   
   NOTE: You must run the Drwtsn32 command from the SysWow64 folder. Drwtsn32 in the SysWow64 folder is a 32-bit version that handles 32-bit User mode exceptions. To run the 32-bit Dr. Watson, locate the SysWow64 folder, and then double-click the Drwtsn32 file.
4. Start Registry Editor.
5. Locate, and then click the following registry key:

   HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\PCHealth\ErrorReporting

6. Set the ShowUI value to 0.
7. Set the DoReport value to 0.
8. Locate, and then click the following registry key:

   HKEY_LOCAL_MACHINE\Software\WOW6432Node\Microsoft\Windows NT\Current Version\AeDebug

9. Set the Auto value to 1.
10. Use this key to verify that the debugger is configured to a setting that is similar to the following setting:

    drwtsn32 -P %ld -e %ld -g

    This setting is typically set when you register Dr. Watson as your default program debugger.

Troubleshoot

• The ShowUI value switches the previous fault error message to new fault error messages.
• The DoReport value determines whether the new error message sends a problem report to Microsoft.
• If you want the previous fault error message or exception error message, set the ShowUI, DoReport, and Auto values to 0.

NOTE: This procedure stops the message for 32-bit program faults.
