On the page below: http://wiki.lyx.org/Windows/LyXWinInstaller
... there is the section entitled "Comparison between the standard LyX-installer and LyXWinInstaller (alternative installer)". The problem is, it does not contain the actual comparison, it only enumerates the features of the "alternative installer"... or maybe I don't understand something obvious? Would anyone be so kind to explain the differences, and better yet - to update this page with the relevant information? Best regards, Michał Skrzypek
