1. No, it is not specific to the game. Most things that require admin privileges won't work for me. When I click on them or try to interact, they won't do anything. No error message or anything.
2. No error message at all.
3. I do have Avira antivirus installed. I have tried to delete it, but that requires admin privileges, which currently isn't working for me.
About letting the game through the firewall, it the same thing. I have tried, yet it required admin privileges.
