New issue 4217 by address@hidden: Pngtopm missing for Windows Users - -danti-alias-factor=2 will fail
https://code.google.com/p/lilypond/issues/detail?id=4217

-danti-alias-factor=1 works fine, but -danti-alias-factor=2
does not convert the output to the high quality images.
I think this might be a familar topic on Windows.

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.

That may be a bug, possibly we should ship netpbm with the windows
binaries?
