Jean,
Thank you. 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.
