RH7: import HTMLHelp

Question

We have cracked our skulls because of this one, and now we
are afraid that this is just a really dumb question.
Simple scenario (and this also happens with other scenarios
of course):
In RoboHelp 7 HTML:
1) create a new Microsoft HTML Help project
2) create Single Source Layout > Microsoft HTML Help
3) start HTML Help Studio (included in the Toolbox), and open
and extract the CHM file
4) close the project
5) import Microsoft HTML Project
RoboHelp will prompt for a HHP (HTML Help Project) file.
However, RoboHelp itself does not seem to create one, when
inspecting the created CHM file (in Microsoft HTML Help, or after
extracting it).
In contrast, we distinctly recall that at some point in time,
we managed to import some HTMLHelp file succesfully (although the
map keys did not make it, but that is alright).
What are we doing wrong? Can RoboHelp really not even import
its own CHM files?
Any help will be greatly appreciated!

Hi, Pet3689,
The project (.hhp) file isn't compiled into the help file
unless you add it to the baggage, so it's not usually recoverable.
However, the freeware utility KeyTools can generate a fairly close
approximation of the .hhp file when you use it to decompile a help
file, so that may be an option to look at.
