maicci: I had the same problem. I then paused the install, disabled my anti virus, rebooted gog galaxy and the install continued successfully after that.
I don't use any anti virus, so it probably isn't that. Thanks for the reply though. I already download twice, that's all the time I am spending on this. I already refunded, maybe I'll buy it again later. When I spend $90 on something, I really don't have any interest in troubleshooting things to make it work. I have installed many other games on GoG with no issues, what is wrong with this one?
