I’ve been using NTSD as a default debugger on my laptop for a while and decided to revert it to Dr. Watson to get a couple of logs. Unfortunately Dr. Watson itself crashed in dbghelp.dll. Loading drwtsn32.exe dump reveals that it depends on both dbghelp.dll and dbgeng.dll. I tried to replace these DLLs with newer versions from the latest Debugging Tools for Windows and found that this change in system32 folder is immediately reverted back to original file versions. Instead of battling against Windows I decided to create a completely separate Dr. Watson folder and copy drwtsn32.exe, the latest dbghelp.dll and dbgeng.dll from Debugging Tools for Windows there. Then I altered “Debugger” value under the following key to include the full path to drwtsn32.exe:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug
Debugger=c:\drwatson\drwtsn32 -p %ld -e %ld -g 

This solved the problem. Dr. Watson now uses the latest debugging engine to save dumps and logs.
