I just installed the new release of lyx-1.6 and I am having problems with the output. When I load an existing *.lyx document it gives me a message: "The layout file requested by this document article.layout is not usable. This is probably because a LaTeX class or style file required by it is not available. LyX will not be able to produce output."
When I look into - Documents > Settings > Document Class it shows that all classes including the standard ones (article, report, etc) are "unavailable". My OS is winxp. I don't know how to fix it. 2008-08-20 wangyq
