I used to be able to double-click xpj files from Windows Explorer to start RH7.
However, after uninstalling RH6 (which had been sitting dormant for months), I
lost the file association for this file type. I tried right-clicking the file
and selecting Open with... > Choose Program > Browse to reassociate it with the
RH 7 .exe file (I selected Adobe > Adobe RoboHelp 7 > RoboHTML > RoboHtml.exe),
but it wouldn't let me add the association. I was able to associate the file to
the RHCL.exe program and create output...

Note that I can still open the project from within RH so I don;t think there's
anything really broken--I'd just want to be able to click on the file to launch
the application like I used to. Do I need to reinstall RH7 to update the
associations? How do I do that?

I don't know why you couldn't create the association but I think I would be
inclined to go for the quick option of uninstalling and reinstalling RH7. In
the long run it will probably be quicker than figuring out the cause.

I'm not sure if this would be any different but if you right click on the XPJ
and click Properties, in there you can change the application you use to opne
the file. How about changing it to something else and changing it back. This
may restore the file associations.

thanks. I tried changing the file association and changing it back, but that
didn't work. But uninstalling and reinstalling RH7 seems to have worked like a
charm and was easier and faster than I thought it would be. Thanks!
