I just removed all of my files and programs reset my computer and installed after effects.
Now I can't click open character animator in the file tab. I see it but it is not clickable....
One bug after another
Sounds like a licensing issue. See https://forums.adobe.com/thread/1872346 - usually if it's dimmed it means something isn't synced like it should be. Sometimes it's as simple as signing in and out and resetting, other times it might require you to reinstall (again). Try those steps on the page - hopefully that helps.
How are you installing After Effects?
All because of Avast anti virus.... I disabled it during install and all my weird bugs went away!
