Lilypond not working

[Hernan Mouro]

I think I followed the instructions in
http://lilypond.org/web/install/windows.html correctly, but Lilypond
outputs an empty pdf.

For installation I used the "Download Without Installing" option, and
then ran Setup again and used the "Install from Local Directory" option.

Here's the test.log:

What am I doing wrong?

Thanks!
