I downloaded the BAT program and G-MAX program. I installed G-MAX with no problem. For some reason, BAT will not install. I get an error message that I do not have SC4 installed, which I do. (SimCity Deluxe does not appear to be installed. You Will need to install SimCity Deluxe in order to use the Building Architect Tools). I am using a version of SC4 which I downloaded and installed from Origin web site.
