No. I just had to modify the path since I do not have a path such as F:/e2015/BibTeX/bibtex/bib/further-4.bib on my Linux box. I suppose your path is OK for you. The log file shows that biber is indeed run (however, it is anyway adviced that you set biber in Document > Settings > Bibliography, since with "standard", LyX uses whatever is set in Tools > Preferences > Output > LaTeX) Anyway, the problematic line is this: 21:38:53.773: read_file 'C:\Users\Bernd\AppData\Local\Temp\par-4265726e64\cache-c38a9b05b97a81d339b4947ba00f0aacefe00497\recode_data.xml' - sysopen: No such file or directory at C:\Users\Bernd\AppData\Local\Temp\p 21:38:53.774: ar-4265726e64\cache-c38a9b05b97a81d339b4947ba00f0aacefe00497\ bda77484.pm line 112. Please delete the folder C:\Users\Bernd\AppData\Local\Temp\par-4265726e64\ and try again. This is a known (and obviously hard to fix) problem of biber. Some times (though very unfrequently) it tries to access such invalid cache folders. Deleting them always solves the problem.
