Hi, Lotus Flower. Welcome to the forum.
Is your HTMLHelp .chm file on a network? If so, you are being
stopped by a Windows security update. Peter Grainge has a full
explanation on his site (www.grainge.org), but you may have some
trouble getting there - I think he's having his server landscaped.
The short form: Windows does NOT want active content (like a
.chm file) running over a network. HTMLHelp was never intended for
network use, anyway - users are supposed to install their help file
on the local PC along with the application. There isn't a lot you
can do about it except a) distribute the .chm file to each user or
b) use a different output on the network. WebHelp was designed to
run from a server, and so was FlashHelp.
By the way, you're not working on your RoboHelp source files
over the network, are you? Don't do that - people have permanently
scrambled their projects. Always keep your source files on your C:
drive. You can back up source files to a network drive, as long
they are local when you work on them.
HTH,
Elisa
