Embedded TEX has been tested with Lilypond version 2.6.5 and should work with all current stable versions up to version 2.10.
Version 2.11 of Lilypond (the development version) has changed its interface, and you will receive the following messages:
C:\Program Files\LilyPond\usr\bin\lilypond.exe returned 2; aborting... C:\Program Files\LilyPond\usr\bin\lilypond.exe: unrecognized option: `-s'
To fix this problem, you will need to change the Embedded TEX configuration. The Embedded TEX configuration steps are described in the Configuration page. Edit the Lilypond application, edit the first step, and remove the '-s' and '-b eps' options from the parameter list.
