help to run bibtex2html in different directories ?

No, I got always the same message but I have not changed all texmf.cnf files, but only the file of the path indicated in this blog. 
Thanks for your help. I have decided to find the solution with org-publish, in orgazing my folders as it is suggested here :

it is maybe a good solution... 

Meilleurs voeux pour cette année 2014, et encore merci !

Joseph
