I got the error message about "escalated privileges" when trying to in stall the creative cloud libraries. I am an administrator on my computer (always have been) with no admin p/w required.File sync is turned on in CC. I tried to remove and reinstall, but always same error message.
Not sure what happened, but after several reboots it now says the libraries were installed. Guess it's been solved unless I discover other issues or if it happens again. I'm always signed on with administrator rights so it shouldn't have had anything to do with "escalated privileges".
