There is a TTF that I can download and see in Finder, but it will not install, "Modelos" or "Argentinas" by Ultrasonicmen. Any clues how to remedy this? I have never had this issue before. Mac OS if that makes any difference.

Always handy to read the comments on a font.

I open with Typelight
Save as Modelos
It's ok.

Also OK on a Mac Claude?

The problem is version number of 0.
