Hi, I installed LyX using the Cygwin installer on Windows Vista.
I installed all LyX dependencies according to Cygwin installer. I also installed tetex-extra, which is supposed to include revtex4 (the latest Cygwin versions of everything, see http://cygwin.com/packages/ ) I am trying to open a document which uses revtex4 and get the message: The document uses a missing tex class 'revtex4' Also, if i try to open help pages, such as "Introduction" or "Tutorial", i get the message The document uses a missing tex class 'article' So it is possible that i have a problem with the whole of TeX installation, although i didn't do anything except running the Cygwin installer. I tried running Tools->Reconfigure, and it didn't help. I see these in Tools->TeX information: /usr/share/texmf/tex/latex/base/article.cls /usr/share/texmf/tex/latex/revtex4/revtex4.cls If there is any more information that i can provide you - logs, version numbers, diagnostics, please tell me. (Sorry, i am really not a TeX expert.) Thanks in advance. -- Amir Elisha Aharoni my band: http://www.myspace.com/tzabari/ my blog: http://aharoni.wordpress.com/
