Error A12E1 when I try to update the Creative Cloud desktop

I get an Error code: A12E1 when I try to update the Creative Cloud desktop on my Mac, OS 10.7.5. I tried creating a different user account but that made no difference. I uninstalled the Creative Cloud desktop app and downloaded a new one from the CC website. Same problem with an Error code: A12E6.

So how do we fix this?
