Hey guys, I am on Windows Vista and I am trying to install "Zone ALarm Pro" to bridge for host. By the way, I have a good connection, I used to get host all the time in Call Of Duty 4 and nobody has complained when I hosted matches in Gears of War. Ok, here is my problem. When installing "Zone Alarm Pro" I get a message saying that I am on a "64-bit" operating system and I am not allowed to install it. "Zone Alarm Pro" cannot work on a "64-bit" operating system? How can I get past this?
