Paul,
Thank you for the reassurance based on your experience. Please bear with me and clarify some procedures. I opened: https://lilypond.org/doc/v2.24/Documentation/learning/graphical-setup-under-windows to read the process. My current Frescobaldi is 3.3.0. So good there. Then further down is the direction: Click on the folder icon and navigate to the lilypond-x.y.z-mingw-x86_64 folder you previously created. Inside this folder, open ‘lilypond-x.y.z’, then ‘bin’, and finally select ‘lilypond’. When was that done? Your assistance is appreciated.

I have installed in Windows the final version of every stable release from 2.6, and the current (and one other) development version so that I can compile and update any lilypond code I come across. Frescobaldi has them all linked in so the correct one is used automatically.

My error in not being precise. I am installing under Windows 10.

Can I keep an operational 2.22.2 while I attempt to download and install 2.24.2? Depends on the installation method. With a package manager on Linux or macOS, usually no, but if you're just downloading the official binaries from lilypond.org, then yes, no problem at all.
