i am opening a document a colleague made, using the same fonts i have - and in my computer - it opens with missing fonts -
saying: fonts are not available in your system , although they are installed.
when i replace all "missing" fonts with the fonts in my computer (it shows the same fonts in the list of fonts) - but when i export to pdf i still get this message that the fonts are missing.
i have tried to re-install, restart computer and still doesn't work.
i have copied all fonts to indesign font library in the program files folder - but still - doesn't work.
What OS do you have?
What kind of fonts?
Are you aware that T1 fonts are not supported anymore with modern OS? Neither WIndows 8 nor Yosemite support it. Only, if you install them in InDesign's Font folder or in Document Fonts it will work.
Another problem could be, that Windows does not support Mac only fonts, only OTF.
