So I dragged it to the all users Font folder and before opening Font Book again, I just opened the file directly from the Font folder and this time it did install the font. So I looked into the user Fonts folder and saw the font file was indeed there it just wasn't read by Font Book or any application. 'Install Font' would summon Font Book but the Font wasn't there, it just looked like it made the effort to install it. I didn't install them, nor by clicking on Font Book. I kept opening fonts just by double clicking the file and then clicking on install.

I'll give FontBook a good rating because it does what it is intended to do and that very well.I read all of your answers and, looking for a solution myself, I think I just accidentally came up with one. Note that this app is from a well established developer, Lemke Software, the creator of Graphic Converter, which I have been using since 2001 with OS 9, even if I didn't see FontBook. For that Font Book provides the basics, including font previews, font sets, font integrity checks and the ability to turn fonts on and off. And as someone else said, it's not a font manager nor does it pretend to be. Still, it bears no resemblance to Apple's Font Book, despite the similar name. It has a wide variety of layout styles to choose from, which might suit someone compiling a type book. That said, if this app provides a service you need, then it really doesn't matter what the name is. Some of the more expensive font managers provided some type book options, though not nearly so many as FontBook. It was quickly adapted for OS X, the first version being compatible with X 10.1.5.

Still, I don't remember seeing it back then. So Apple stole the name and added a space. I checked the Limkesoft website and it's true, FontBook was available before OS X there is a classic version for OS 8.6 through OS 9.

Font Book has been a part of OS X from the beginning.
