can't uninstall older version of MuseScore -- greyed out in "Applications" window

Okay -- got musescore 3.6.2 removed. Thanks so much.

Based on the locate command that you gave me I also tried this to find Musescore4 Portable and got this:

locate *portable
/home/christopherlaurenzano/.local/bin/mscore4portable
/home/christopherlaurenzano/.local/bin/musescore4portable
/home/christopherlaurenzano/.local/share/flatpak/runtime/org.gnome.Platform/x86_64/45/547c38809093f20a153446421224c4d197bc8ce24d3c5cdd4b ab978bbf9b3c83/files/lib/systemd/portable
/var/lib/flatpak/runtime/io.elementary.Platform/x86_64/7.3/d9fc7a37330ed6b142000e020f6c74eac5905daba9af1b7002 8a583dca8f03d4/files/lib/systemd/portable

I've highlighted in blue the files with musescore in them. I'm assuming that the other files don't have anything to do with them, but I'm not sure. Was wondering if you could let me know if I can use the "remove" command to eliminate those two files, and how to correctly enter it. I don't want to remove files that I need.

I've no idea about those portable versions but I suspect they may be flatpacks and those unmarked files in the list may be needed for those flatpack versions to run

Perhaps just move them to Trash rather than remove them completely; you can then restore them if needed.

I've never used flatpacks hence my lack of knowledge.

Honestly I don't know how they were installed -- it had been so long since I've used them. They've got to be somewhere on my computer, but I wouldn't know where to look for them. I can only guess and say that I installed them from the app center in elementary OS. But I can't even be sure about that.

This will find them all:

> locate musescore

This will narrow it down a bit:

flatpak list|grep musescore

When MuseScore gets updated via Flatpak it dumps an appimage in Downloads:

ls Downloads 
"1.All-DL's"MuseScore-Studio-4.4.3.242971445-x86_64.AppImage

Seems rather silly to me due to this:

locate -i appimage | grep -i musescore

Nothing found.
