Re: pngtopnm missing?
I'm sorry I still can't answer your exact question, but I can give some pointers. pngtopnm is a standard image file format converter on unix boxes, and so I guess Lily assumes it's there for some of its operations, and it isn't on Windows. Hence the error message. In my experiments, using --png with -dresolution=nnn gives exactly the same output as -dresolution=nnn/3 -danti-alias-factor=3 - so it appears not worth using the anti alias factor at all. Accepting that you will never get an image file as good looking as PDF, since PDF scales, then something like lilypond --png -dresolution=900 should give you a better image than you need.
