CEP Extensions not showing in menu if installed to system Library [SOLVED]

[notbyhalf]

It's been like this for a little while and across versions of After Effects. I don't know what setting I have changed along the way, but After Effects only displays Extensions installed to ~/Library/Application Support/Adobe/CEP/extensions/ but not /Library/Application Support/Adobe/CEP/extensions/

Works as expected on another computer of mine. Any thoughts?

SOLUTION

I trashed my CEP folder in /Library/Application Support/Adobe/ and re-installed an extension using ZXP Installer from aescripts.

macOS Mojave 10.14.6
After Effects 17.1.2

Probably caused by folder permissions getting corrupted on Mac, I've ran into this before.

Though not related to the install path, one may have the same problem if the version number does not respect a given regular expression.

That regular expression that Premiere Pro / CEP demand depends on the manifest version number. You can find it here for example: 

\d{1,9}(\.\d{1,9}(\.\d{1,9}(\.(\w|_|-)+)?)?)?

Basically, a version named 2.0.1-alpha2 will not match and your extension will not show up in the menus.

On the other hand, a version named 2.0.1.alpha2 will match and make your extension show up.
