How to install "Just-in-time" debugging (mse.exe) by default in Outlook 2002 Pro

Hi,
I would like to know how I can set the Just-in-time debugging tool
(Microsoft Script editor:mse.exe) as my default debugger in
Microsoft Outlook 2002 (version pro). One of my collegue have it set
by default. In do not know if it is because he is running Office Pro
2003 or
because he have installed another component that have set it by
default. He does not have Visual Interdev installed. Is there a way to
set it in the registy?
Thanks
