Is this only with a single project? Try one of the sample projects and generate those. Do you have package_x.xml files then?
Thanks for your reply.
The problem is with every project I work on.
I tried one of the sample projects (Salesbuilder) and, as always, got no package.x.xml files.
In that case I suspect that there is an issue in your installation. I would recommend uninstalling RoboHelp and installing it again.
I may be unrelated, but I had a similar problem with RH9 when IT installed RH through a silent install. If RH was installed that way, the packages were not generated. If you manually installed RoboHelp, everything worked fine. I still don't know what caused it, installing manually worked for me and my colleagues.
