I ran into this problem last night, while trying to preview my first C4D file in after effects. I tried various internet fixes but none worked. This morning I remembered during install, certain CC apps would stall due to something called Adobe Crash Daemon, and the fix was to quit Adobe Crash Daemon in the mac activity monitor; the install would then continue to completion.
So I tried it for this problem, and it worked! Not sure if this is at all related, or if purging and closing the app again was the real trick, but something changed and I no longer get the error message.
Hope this helps.
