Perpetual Character Animator CC install and fail

I'm on Mac OS10.13.2,  Anyone else having an issue where CC keeps notifying you that character animator needs to be updated but when you go to update it, it fails? Basically every time I log on to my computer, I'm getting a notification to update Character Animator.   But installation fails.  Getting this message.. 

"Update failed. Unable to move the file. Rename the file and then try again."
