Installing Adobe Creative Cloud Offline?

Greetings,

A system where I work has proprietary information. Some of these are video files which I would like to open and export from an Adobe After Effects template I created. Unfortunately, I can't access the internet from this secure system. My question is, how do I get AE (any version CS4 and up will do) onto a system without internet? Is something like this out of the question for an online dependent system like the Creative Cloud?

Thanks!
