lilypond-book under winXP

[Morten Lemvigh]

I'm having some problems running lilypond-book under WinXP. I get the
same error no matter what I do. Even if I type in the
lilypond-book-example from the Users Guide. The errormsg I get is
written below. I just upgraded to version 2.8 but the problem was there 
in version 2.6 as well.

If anyone could give me a hint, as to where I should start looking for
the problem, I would be very thankfull!
