Part of the idea behind COM was to make things easier, particular with
versioning. They are upwards and downwards compatable with additional
features available as additional interfaces, but the same basic set (the DOM
with some MS extensions) are supported in all versions. I have run the same
software with out compiling on all versions with no problems.

It is the Microsoft XML component.  No requirements on the part of GNATCOM
other than NT service pack 3.0 or greater or 9X or greater.

MSXML comes with IE4. Although MSXML is not perse dependant on IE4 (the
other way around is another story).

Just make sure they have IE4 or greater and everything should work. On 95
look at IE4 as a service pack that is required. On NT, IE4 is required for
the option pack, etc. IE4 or greate should be on the machine.
