Re: Lilypond won't start, non of the versions.

Lilypond is not supposed to start, at least not in the way you are 
expecting. Lilypond works like this:

1. You type a text file containing music instructions.

2. When you finish typing, you give a command for Lilypond to interpret 
your file.

3. Lilypond follows the instructions in your text file and spits out a 
page of music.


You never really "see" Lilypond on the screen; you aren't supposed to.
