Hi,
Excuse me the last email I confused export with import.
I recently convinced my brother to use lyx but now he can not open his
files que created using latex. I tried to export them also with my lyx
configuration and it is not working also. I have perl and python
installed so I think that is not the problem. He created his latex
documents with the latest version of Miktex and he uses a class called
ifacmtg and a paquet called harvard to include bibliography cites.
I hope someone could help me, thanks
Jose
