Recently a friend and I installed Archeage jp, and got it to work no problem, however we tried to install the game a friends computer and no matter what method we've tried (ill list what we've done below) it keeps getting hung up on this spot. Also we have the same VPN on all three computers. (pic attached below)
*Install from the site directly
*copy data from an external to the computer
*Make a new account and try again

The post was a bit rushed so sorry for grammatical mistakes. I'll be happy to provide any more info that may be needed.
