I've got exportation issues. I couldn't export to HTML or .odt, only to .tex or LaTeX. I'm running Lyx on WinXP. I was told, that Lyx doesn't like spaces in directory names, and as it was installed to the "Program Files" folder, I thought that's the problem, and tried to reinstall into another folder. Now Lyx doesn't start, instead it gives an error message:
"LyXTextClassList::Read: no textclasses found!" (I've installed MikTex and ImageMagic, which came bundled) -- Zsíros Levente
