Hi, By mistake, I already post this question onto gitlab (issue 6286) instead this user list.So, I try to get help here.
I downloaded "Windows: LilyPond 2.22.1-1 for Windows 2000, XP, Vista, Windows 7, 8 et 10. " from lilypond.org and run installation onto Windows XP family 2002 service pack 3, 32 bits. Setup program runs perfectly (no warning or error like only 64 bits OS supported..). "Show details" confirms at the end "Completed", with no errors. I launch lilypond from XP Menu : Error message : Lilypond-windows. exe "This application can not start because the setup of application is wrong. Reinstall to resolve this issue" (exact message in french language : "Cette application n'a pu démarrer car la configuration de l'application est incorrecte. Réinstaller l'application pour résoudre le problème). Remove and another setup is same. I try to launch from console, after setting variable environnement (path). Error : "The system can not execute this program" (Le système ne peut exécuter le programme spécifié). It seems that python installed with the setup pack make trouble because this is a 64 bits version, that clearly answered python.exe in LilyPond /usr/bin subfolder. 32 bits Python for XP seems to oudated back before 2015 for a additionnal install from python official website. My question on gitlab results to no support for old OS, despite Lilypond download page ensure windows 2000 and XP support (https://lilypond.org/windows.html). Perharps someone can help me, Lilypond likes wonderful software. Thanks.
