What version number of AE are you using?
Are you still triggering this dialog box in your standard workflow, or have you fixed this issue? Please give us an update and if you need more assistance with this perplexing issue.
did we ever get an answer to this question? Only today have i started getting this error when i open a file that i don't have all the fonts for. "Unable to initialize the sync missing fonts dialog". Then the project wont open.
Running CC 2017.2 (184.108.40.206), OSX 10.11.6
Can you import that project into a brand new project?
I got this error when I was sent a project without the fonts. After I quit and installed the fonts it opened fine.
Probably a problem trying to sync missing fonts so having the correct ones will prevent this error. Possibly.
I'm having the same issue
I've had this happen with 2 projects now. This happens when you don't have fonts that are used in the project. The work around is to install all of the fonts used by the project. It also occurred to me that maybe enabling/disabling font sync might help:
- In the Creative Cloud desktop app, choose > Preferences > Creative Cloud.
- Click Fonts.
- To enable or disable font sync, select either On or Off from the Typekit On/Off settings.
If anyone wants to recreate this error, they can probably do it by making a AE project, using a special font in a new comp, the quitting and removing the font. Or maybe moving to a different machine without the font.
