So from reading this, I don't get what I need to do to work the game I am using Nortan 360 and I thought to just uninstall the game and re-DL it to make it work but I was wrong. I only have a disk write error when I try to download the game again.
It says in the text
"This can be easily solved by allowing the DRG game files when prompted, or releasing them from quarantine if they have already been blocked. PLEASE NOTE: It is not enough to close your anti virus, as that will still keep the files blocked."
Try that and see if it works
