FWIW, with the registry change you can still use
the majority of the functions of the web authoring
tools, if needed. By marking it to not install
you lose all of them.
A useful feature of the Word 97 web authoring tools
is the ability (not continued in newer versions) to
'melt' web code from the document into the source code
by typing or pasting it in the document then applying
a web style to it (Normal-web if I recall correctly)
to that text then saving adn reopening the document)
======
Either of the methods I suggested should preclude the appearance of the
HTMLMARQ.OCX error message in the first place, which by your own
admission the registry hack may or may not fix. >>
