windows debugging debugview

I've installed DebugView 4.79 on Windows 7 and Windows 8 64 bit machines and a Windows 7 32 bit machine. On all of them I see no output from DebugView when starting it as Administrator. I'm trying to debug an application that uses a CLI/C++ component with ATLTRACE calls in it.

I've enabled capture events, capture win32 and capture global win32 and see nothing so I'm not sure what's going on.

By default DbgPrint() output is disabled in Vista/Server2008 and above. The following setting in the registry should enable the debug prints.

  1. Open up the registry
  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Debug Print Filter
  3. Add the following value DEFAULT : REG_DWORD : 0xFFFFFFFF
  4. Reboot
