No because Works and Office are two entirely different suites of
applications. What he WILL have to do (AFAIK) is to save all the Works
documents into a format that Office can read, if the versions are not in the
files-of-type boxes.....if you see what I mean....
Please also note that Works is *NOT* a qualifying product for Office XP -
but it is for Office 2003 (though that's not much good if you're using 9x or
NT as 2003 requires 2000 (SP3 or later) XP or Windows 2003).
