I am trying to install LyX, which is a typewriter program for LaTeX, but I'm having trouble doing it.
Really I tried tons of way to do this, but the error message is the same:
LyX: No textclass is found
LyX will only have minimal functionality because no textclasses have been found. You can either try to reconfigure LyX normally, try to reconfigure without checking your LaTeX installation, or continue.
(Press the button) Reconfigure (or) Without LaTeX (or) Continue
