Answer 1

Not my scooter just posted an announcement:
1) If the font is not installed in Windows 7 or 8.1 with an error message like "the file is not a font file" - try downloading the same font from another source. If the font is not presented as a ttf or otf file, then it can be converted using any online converter. For example, if you have a woff file with a font, search for a converter on the Internet for "woff to ttf" and convert it.
2) If the font is not installed in Windows 10 - in this case, the instructions above apply, but there is an additional nuance. Many users noticed that ttf fonts might not install on Windows 10 with built-in firewall disabled with the same message that the file is not a font file. When you turn on the "native" firewall, everything is installed again. Weird bug, but worth checking if you're running into a problem.
