Hi guys,
Unfortunately, none of the previous answers solves my problem.
I try to install fonts. According to Windows that also works but I cannot see the installed fonts in the Windows Fonts folder and neither do they show up in Illustrator.
When I copy a font file into the Windows Fonts folder it says "The "xxxxxx" font is already installed. Do you want to replace it?" - I click yes, but still - the font does not show.
It's not a problem of the font file as it was working previously. Same happens to hundreds of other fonts. Says they are installed but they don't show and they are not selectable in other applications.
Thanks for your help!
