Avenir Next Bold .ttf font style showing as missing Windows 10
This font issue seems to be originating in Adobe programs on Windows 10. I was given a file from a Mac version of Adobe Illustrator. I have worked between Windows and Mac and back again on a weekly basis at my previous job and font recognition has not been an issue.
The file that was given to me was a packaged file with a "Fonts" folder containing multiple .ttf and .otf fonts which I installed on my Windows 10 PC. The Avenir Next font family was packaged in a .ttc file which I have never seen before.

After installation on my PC it says that there are 12 font faces and it shows up when I go in the folder in Settings and in Control Panel.

But when I go into the AI file I was given, all of the font family shows up except for Avenir Next Bold, which it shows as missing. This is true in every Adobe program I have tried ie. Photoshop, and InDesign so far.


This is incredibly frustrating and upsetting especially because I emailed the person who sent me the file and they said that they sent me all the fonts I would need.
I would appreciate some help as this job is incredibly important to me if I am going to be able to work from home on a Windows PC.
Thank you in advance.
