I guess MikTex got installed properly .
when I try to start lyx it is showing: The Layout file: article could not be
found. A default textclass with default layouts will be used . LyX will not be
able to produce correct output.
And the very beginning before the previous message it shows: LyX will only have
minimal functionality because no text class have been found. You can either try
to reconfigure LyX normally, try to reconfigure without checking your LaTeX
installation, or continue.
Please, guidelines needed to make it work.
Thanks.
