Hello,
I downloaded and unzipped lilypond-tools-2.6.0.zip.
I then ran abc2ly.exe on a xxxxxxxx.abc file; this gave me
a correct xxxxxxxx.ly file, which I fed to LilyPond, and
that gave me both a correct PDF file and a correct midi file.
But when I ran etf2ly.exe on a Finale Notepad file 2005test.mus,
I got a 2005test.mus.ly file that contained only one single line:
% lily was here -- automatically converted by etf2ly from 2005test.mus
That .mus file was produced directly with Finale Notepad 2005;
it contained a 2-bar scale.
