This looks really weird! I tried 1.4.5 on my Windows 95 
installation and I didn't experience any similar problems.
I'm sure you have tried several examples, including
examples from /usr/lilypond-1.4.5/input/*/* so it's not a 
problem with your specific file. Actually, I didn't do a 
virgin install but used, an old MikTeX installation, but
the rest of the programs should be up to date.

I noticed one severe problem, though, for examples that 
use the Computer Modern font with other sizes or shapes than 
cmr10. Lilypond isn't able to find the tfm files in the
MiKTeX directory tree and there is no mktextfm available
to generate possibly missing sizes. Maybe this works if
you install the MiKTeX version from www.lilypond.org, but
I doubt is since the default search path in the kpathsea
library is .:{/usr/share/texmf/fonts,/var/tmp/texfonts}/tfm//
How is this supposed to work in the Windows installation?
The old installer by Jeffrey Reed included a directory
share/lilypond/cmtfm/ with all the tfm files, I don't
know if there's any better way unless we can find a way
to ask MiKTeX to generate tfm files on the fly.
