Wh2robo.dll error received on running Winhelp 4 file

Question

A colleague is experiencing a problem with his help file. On
launching the Winhelp 4 compiled file, this message appears. Cannot
find or load the file wh2robo.dll. This does not happen on my
machine or the other help author, but it does on others. The
message then goes away and a second error message displays: An
error exists in this help file. Contact vendor for an updated help
file (1024).
The file displays, but with these errors.
Any help is appreciated.

Answer 1

I am on RHX5, Word 2003.
wh2robo.dll appears in two different Program Files folders on
my PC (standalone): one is the RoboHelp folder; the other is a
project app folder in which, uniquely, I prepared the Helpfile
(otherwise I worked within a specific project folder within the
relevant Client's folder eslsewhere).
The two files are themselves different. The RH file is noted
as, yes, an Active Edit file, Macromedia, 76Kb and dated
25/03/2004. The app file has no accreditation, is logged at 40Kb
and bears the same date as does the final build of the relevant
Helpfile.
No others of my archived project files contains wh2robo.dll.
It isn't on the Ship List for WinHelp 4 (nice and short: *.hlp and
*.cnt only).
You don't say whether either you or your colleague has
wh2robo.dll; if so, where; and which RH version you are each using.
Perhaps you could let us know?
