Can't install Elder Scrolls Online

I’m on Endeavour OS. Installing ESO from script. I keep getting these errors when trying to install the standalone edition:

lutris-wrapper: /usr/bin/bash
Started initial process 13214 from /usr/bin/bash /home/olorin12/Games/the-elder-scrolls-online/tmp/extractlauncher.sh

Monitored process exited.

I abort the install but don’t erase anything. When I go into the ~/Games/the-elder-scrolls-online/tmp/Install_ESO/InstallerData/Disk1/InstData/ directory and try to unzip that file, it tells me that it’s not a legitimate archive type.

Any ideas?
