Games : Is there a way to download ESO files from another PC?

As The Elder Scrolls Online went free-to-play, I wanted to reactivate my account and see what has changed.

Unfortunatelly, I deleted ESO from my PC and by now I've got a very slow internet connection. Downloading 32 GB of files would take a very long time. I calculated it painstakingly and my result is: forever.

Therefor I'm looking for other solutions. I've bought just a key online, so a hard copy isn't existent. Maybe Zenimax provides some solutions where I can download the setup files seperately to get it on a USB stick?

Is there a way to download the needed files for playing for ESO on another PC to make it more or less portable?

(For clarification: I just need a way to copy files to my PC so that the game works as intended.)
