I completed a search on this forum and general Google - but no answer to the issue which resolves - when selecting help files they are not available.
Help file 'kicad' could not be found.
I downloaded the pdf documents and placed them in /usr/share/kicad.
I then added to Preferences -> Configure Paths selection - added KICAD name and the path to the pdf documents - and still not working.
Is this a bug or is my NAME (KICAD) incorrect etc.?
Any help gratefully received.
I am using Fedora 25 64bit.
Thanks and Regards,
