Re: run error Lilypond-book on Windows 10

[Archer Endrich]

Hello Carl,

That was a good idea.  When I enter 'python' on the top level of my C:\ 
drive, it says that the version is 3.7.4.

However, there was an earlier version in my 2.18.2 Lilypond, so I 
renamed that to disable it and added a full path to my 2.22.1 
lilypond-book in my batch file.

I can't find any other PYTHON on my system (e.g., in Program Files).  I 
haven't reinstalled any other Python since moving to Windows 10, which 
involved a completely new hard drive.

The error message about line 376 no longer appears, but the .tex file is 
not created, so pdflatex has nothing to work on.

When I run the batch files, Windows keeps asking me "How do you want to 
open this py file?" but does not give be a Browse option. Notice the 
"access is denied" message in the command line display after running.  
(I haven't actually been able to specify that I want LilyPond to run it.

This is the display:

C:\P3L\lpbk>ALMdurasnumber.bat

C:\P3L\lpbk>C:\Lilypond2221\usr\bin\lilypond-book --output=out --pdf 
ALMdurasnumber.lytex

Maybe David Wright's suggestion was correct, namely that "Something 
looks odd about C:\Lilypond2221\usr\bin\lilypond-book.py
in that I would expect either C:\Lilypond2221\bin\lilypond-book
or C:\Lilypond2221\LILYPOND\usr\bin\lilypond-book where LILYPOND
is either lowercase or camelcase (I have seen both). "

Perhaps lilypond-book needs that path -- but my normal LilyPond notation 
works OK with my 'odd' path.

So I'm still puzzled.
