In general, the way to execute convert-ly.py is not with convert-ly.py <options>
But instead python convert-ly.py <options> If you create an executable batch file somewhere in your PATH called convert-ly, with the contents C:\Program Files (x86)\LilyPond\usr\bin\python.exe C:\Program Files (x86)\LilyPond\usr\bin\convert-ly.py Then I expect you can just call convert-ly <options> But I don’t use Windows now, so I haven’t tested this. I do use the equivalent in MacOS.

I went to the section 2.2 of the usage manual and popped the following into a windows 10 command prompt (with administrator privs) C:\Program Files (x86)\LilyPond\usr\bin>forfiles /s /p "C:\users\peter\Lilypool\Music_Files\Bouffil" /M **.ly /c "cmd /c convert-ly.py -e @file" The result was 'convert-ly.py' is not recognized as an internal or external command, operable program or batch file. Etc etc for each .ly file in the folder I have cd’d to the Lilypond usr\bin folder so I don’t think the three “s are needed here, but who knows Where did I go wrong? For no particular reason I then uninstalled anaconda and python 3.8 the result (after reboot) was that the same command string produced a response for each .ly file in Bouffil. The response was a pop up box saying that no app was available for that file. The Command Prompt then froze and I needed Task Manager to close it. Clearly these other pythons have interfered with Lily somewhere and may have a bearing on my other recent issues. Does anyone else play around with Python outside of Lily who might know how to keep then separate. Regards Peter
