A customer has supplied a font, Charoe-Medium.ttf, that will not show in the font menu in InDesign 17.2 x64, Windows 10. It is installed on my machine and is available in Illustrator, Photoshop, and MS Word. I installed it on another machine with InDesign 15.0.2 x64, Windows 10, and it works just fine. I had a friend install it on a MAC and check it in his InDesign, which worked. I have reinstalled InDesign, restarted several times, and have tried several different copies of the font. I have tried TTF and OTF, nothing works. What's going on? Any thoughts or suggestions?
