Is microsoft word a requirement for robohelp to generate pdf files?

Hi,

I am trying to get RoboHelp 11 to generate a pdf from a linked framemaker project. But I keep getting a error pop-up stating that robohelp can't find a Mircosoft Word installed on my system.

I don't use any word files in the frame maker project.

And when I try to make the PDF dircetly from framemaker there is no problems with not having Microsoft Word installed.

Thanks for the help

Alex
