Here are a few tips for using Windbg.

Debugging a 32-bit application on 64-bit windows

Have a look at: http://msdn.microsoft.com/en-us/library/aa384163(v=vs.85).aspx

To summarize one has to use:

  • Use the !load wow64exts command to load the debugger extension.
  • !wow64exts.sw: Switches between x86 and native mode.
  • !wow64exts.k [count]: Dumps a combined 32-bit/64-bit stack trace. If `count' is specified, the command dumps the first count addresses in each stack trace.
  • !wow64exts.info: Dumps basic information about the PEB of the process, the TEB of the current thread, and thread local storage (TLS) slots used by WOW64.
  • !wow64exts.r [address]: Dumps context for the specified address. If address is not specified, the command dumps context for the processor.
