Better Collada Exporter doesn't work

And by that I mean it doesn’t even show up. I have the latest stable version of Blender, as updated by Steam, and I need to create assets for my game project, Nach, in the latest version of Godot. I’ve tried the one directly from Git and I’ve tried the one available on the Godot website.

Apparently Better Collada Exporter is the very best option for exporting assets to Godot. If only the plugin would actually install on Blender. I’ve tried all the methods to try and install the plugin (which includes installing it via the user settings, manually dragging and dropping the files to the addon folder in the installation directory, manually dragging and dropping the files to the addon folder in %APPDATA% > Roaming > Blender).

One of two things happen:
1- The addon shows up in the addon list and can be activated, but there is a warning on the addon that it will only work on the latest version of Blender and doesn’t show up at all in the export menu.
2- The addon doesn’t even show up in the addons list.

This is frustrating me to no end because almost every tutorial, every feature (like creating custom collision meshes for Godot) requires me to use Better Collada Exporter, and meshes exported to GLTF can be imported into Godot well enough but starts puking up errors whenever I try to test the scene.
