Does it result from wrong installation?
The most likely reason is that you either do not have LaTeX installed or
have it installed improperly. On Windows, the most common LaTeX
distribution is MikTeX. If you don't have MikTeX (or some other
distribution), you can do one of the following:
a) download and install MikTeX (http://www.miktex.org); start LyX; run
Tools -> Reconfigure, and wait for it to complete; then close and
restart LyX; or
b) uninstall LyX, download the complete installer
(http://wiki.lyx.org/Windows/Windows -- you want the 80 MB "bundle") and
install that.
Note that LyX needs a few other programs besides LaTeX, notably
ImageMagick (for image processing) and Ghostscript. If you are missing
those as well, take option (b) above; the bundle comes with everything
you need.
On the other hand, if you think that you have a working copy of LaTeX
installed, open a DOS window and run 'kpsewhich article.cls'. It should
tell you the path to the article class. If it fails to do so, your
LaTeX distribution is screwed up. If DOS says kpsewhich is an unknown
command, you need to get your LaTeX bin directory onto the system
command path.
