title: Debug a MS Word Macro Invoked from another app using OLE
body: <p>I have a C++ app that invokes a mail merge in a word macro in a .docm file. The macro works on Windows XP but not on Windows 7. I want to debug the macro first in Windows XP where it works then move to Windows 7 where it doesn't. </p>
  
  <p>I have set a break point in the macro to debug but I'm unable to get the debugger to engage when invoked from my app. I used to do this many years ago (and versions of WORD). Is it still possible to do this, I've exhaustively googled this for the last day and a half and I've come up with nothing.</p>
