There is a bug in the set-up.exe that requires logging into the cloud to install Creative Cloud. Why, Adobe….just why?
Solution
Taking a different “setup.exe” from an older installer works.
Update 10/10/2018
4_7_0_400, 4.7.0.400 still requires an older set-up.exe to get around the ‘cloud’ requirement during installation.
