thanks for your quick reply,
you are right, users are running he help file from a location
in the server. Actaully I am planning to place the help files in a
server in the customer location where users will be able to reach
the help system through a link.
The information you provided were helpful and as I read the
contents of the attachment, I understand that I have these options:
either to change on the registry of the users' machines
or change my output to Webhelp.
but my big question, why it works in some machines and some
not???
