We had a similar situation. We installed our RH X5 a few
years ago, then within the last several months, every author
(except me) couldn't see the Contents pane at all on their local
machine or if they were viewing the output only (outside of the
project) on one of our network drives. They also saw the
"whskin_pdhtml.htm" error also whenever they tried to access the
skin editor.
I suspected, but was never able to prove, that the issue was
related to how IE interpreted Javascript and/or various add-ons
based on a user's permissions. I even tried to find out if a recent
Microsoft security patch was the culprit, but still couldn't be
100% sure.
Our solution was to uninstall RH X5, get local box admin
rights granted permanently to the user of the PC, then reinstall
RoboHelp X5. We've done three of these in the last two weeks and no
one has had an issue since. We've found that having local box admin
rights granted to the user permanently rather than temporarily
seems to work.
Look for an Adobe Knowledge Base article on Uninstalling
RoboHelp. I would include the link to it here, but the Knowledge
Base search feature seems to be on the fritz today. I copied the
uninstall info into a Word doc a while back and I have it on file
if you need it. Let me know - my email is jreinhard@paychex.com.
