⚠️ If you want Blender to see the custom fonts you install, you need to choose “Install for all users” (it requires admin privileges) rather than simply “Install”.
Here is how to do it (my windows is in french but you get the idea) :
Do not click Install but instead choose “Show other options” (or something like that in english), at the bottom of the menu when you right click.

Choose “Install for all users”, with the little admin shield in front of it.
