TexLive can't find Lilypond anymore

[Brayanokles]

Hello,

I have installed a new version of Lilypond.
Ever since, TexLive doesn't see Lilypond anymore.

Here is my test script:

\documentclass[a4paper, 11pt]{article}

\usepackage{lyluatex} 

\begin{document}
	This is a MWE.
	
	\lilypond{ c' d' e' } 
	
\end{document}

The result:

(c:/texlive/2020/texmf-dist/tex/latex/graphics/lscape.sty))'"lilypond"' is not recognized as an internal or external command,
operable program or batch file.
c:/texlive/2020/texm

l.8 	\lilypond{ c' d' e' }
                        
? 

How can I fix this?

You should ensure that lilypond is in your PATH environment variable.
In any case, manually adding the path of lilypond should solve the problem:

\usepackage[program=/path/to/lilypond]{lyluatex}

[Brayanokles]

Path = C:\Program Files (x86)\Lilypond\lilypond-2.24.0\bin ??

[jperon]

The executable should be included:

\usepackage[program={C:/Program Files (x86)/LilyPond/usr/bin/lilypond-windows.exe}]{lyluatex}

Given there are spaces and you’re and Windows, perhaps you should replace / by \, and perhaps add quotes around the path… not sure, but I’d be interested if you could tell me what eventually works (for future reference).

[Brayanokles]

in bin, there is no lilypond-windows.exe file. Where can I find it?

[jperon]

Perhaps it is lilypond.exe. I made a copy - paste from an old issue, so the names might have changed.
