The error message looked for cls file. I guess it is because the installer bundle only offers basic setup of Miktek, therefore most of document classes are not available.
Use complete installation of Miktek might fix the problem. Regards, Hayu On Fri, Apr 11, 2014 at 11:41 PM, Scott Kostyshak <skost...@lyx.org> wrote: > On Fri, Apr 11, 2014 at 5:27 PM, Nasser M.
