I don't know because when I started to install a second copy I got a warning message, "A previous installation of Age of Conan has been detected. It is strongly recommended that you uninstall the old version before you proceed." This made me think that a second install might screw things up and I would have to uninstall and start from scratch. Since the first install took over three and a half hours, I just couldn't face the thought of having to do it over.
