I installed a font (.otf) that can be viewed in the Font Settings and in the Windows Font Viewer, as well as in websites where I can upload font files to see them. However, when I try to use the font in Word 2016, it is displayed in Arial.
I tested this with another downloaded font and the same thing happened. The font also doesn't display on Excel or Powerpoint, though on Powerpoint some of the ligatures have an effect (the result looks like two characters squashed together.)
I have checked the windows registry (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts) and the font file doesn't seem to be there, but from what I can see only .ttf files can be seen there, so I'm not sure whether this is relevant.
Edit: I have installed the .otf file on another computer and it works in Word 2016 on that computer, so it is probably something to do with my computer and not the font file.
