I see Character Animator in C:/Program Files/Adobe
Maybe do a uninstall/reinstall of Ae? (just guessing)
Did you install to a custom file path? What do you see in C:\Program Files\Adobe\Adobe Character Animator (Preview)?
I have just uninstalled and re-installed.
It is not there at all.
It does not install it, also missing from the file paths you have mentioned!
It was just fixed by remote by an Adobe support representative.
He did just what I did: Signed in and out, uninstalled, and re-installed (for the 3rd time...), and it worked.
