After Effects error: File "(filename).aif" cannot be opened, it may be in an unsupported format. ( 86 :: 1 )
Issue: After updating to 15.10, After Effects stopped recognizing .aif files (see image).
Error message when opening any project with .aif files in them: After Effects error: File "(filename).aif" cannot be opened, it may be in an unsupported format. ( 86 :: 1 )
-For clarity, this happens on all audio files in any of my projects, not just the one in the screenshot.
-Replacing the files via Replace Footage does not solve this issue - it won't recognize any of the replaced audio files either, you get the same error.
-Reboot does not solve this issue.
-Uninstall / Reinstall (with removing preferences chosen) does not solve this issue.
Workaround:
Rolling back to 15.0.1 allows me to use the projects as expected, and I do not receive the error. Not exactly a sustainable solution, though.
Any ideas on what is going on here?
