Hi there,
I've seen a similar question to this before through a Google search and I tried the advice listed such as placing the affected fonts in: C:\Program Files(x86)\Adobe\InDesign CS6\Fonts; as well as searching for fonts with a **after its name. Doesn't work. The files originated in CS5 and pops up saying there are two missing links (fonts) which are Avenir Book and Avenir Black. I've done the "Find Font" and the only one that shows is Avenir Book. Avenir Black isn't even there, even after re-installing and relocating to the new folder. Secondly, even after I save the file after "finding" Avenir Book, upon re-opening it still says it's missing. Is there anything else I can try-short of uninstalling InDesign CS6 (I still have CS5 installed)? Also, I'm not that familiar with InDesign, it isn't a program I use much.
Thanks!
