Thank you for the suggestion. I need to clarify.
I did not have the Service Pack 2 CD to insert into the
drive, because my base system was built from an image, and we do
not have CDs for the operating system. We do not have CDs for most
of our other software, either, because the company buys site
licenses and makes software available for us to load from a server.
However, my problem occurred not when I started the word day, but
immediately after I uninstalled some trial software and got the
message that some Service Pack 2 files had been changed and to
insert the CD which I didn't have for the reason stated. The folder
is writable, by the way, and RH makes a CPD file but then can't
build the database.
Although we have experienced problems after receiving updates
through SMS, no one else is having a problem with RoboHelp...just
my machine...so I doubt it was an update, and there are no updates
in Add/Remove Programs list around the date of the failure. The
projects themselves are not corrupt, because other people can take
my zip files, unzip the projects, and work in them just fine.
We have tried repairing Service Pack 2 twice (in different
order with respect to the RH install), and that has not fixed the
problem. This is why I was hoping someone might know which file or
files RH needs to launch a project. Although I have been cautioned
against it, I am really tempted to uninstall and reinstall Service
Pack 2.
I was also tempted to use a program I found online that
promises to clean up the registry, Windows, and Service Pack 2
files. The initial scan claimed to find a large number of "Errors,"
but I would have to register (and probably pay for the application)
for it to actually fix my system...and it might not work. And it is
against company rules to install software that was not purchased
through our software purchasing system, so I really couldn't do
that. If it had been my own PC at home, I would have.
