But the puzzle remains as to why some folkes have the Office12 mso.dll and
others do not.
one possibility is that one might have to have a compiler, such as VB 6 or,
some other language, and not just office.
The Compatibility Pack may install the MSO.DLL version in question. Of
possibly one or another of the Office viewer apps (though not the PowerPoint
viewer ... I just checked that).
