are you asking me how to hack this game? You won't be able to do much with this title if you are trying to work on it while EAC is running, sorry
This seems to be a security issue. I had the same issue when I forgot to run as admin, doing so manually or setting it in compatibility mode was the only thing that did it for me. If doing so doesn't work there is something else going on, security policies aren't my speciality. If you've jumped through the hoops as instructed it works perfectly.
