This is a duplicate.
you find the right entry:
we are using RoboHelp for Word X5.0.1 (Build 606) with
Windows XP (ServicePack 1) and Word 2003 (SP2).
Everything is working fine, just generating Printed
Documentation makes trouble. With Word 2003 the topic order in the
manual is completely wrong. It's not the TOC order and it's not the
order of the source Word document, it's a total lack of order.
If I generate the Printed documentation (same project) on
another PC with RoboHelp and Word 2000 everything is alright.
Can anyone solve this problem?
