In order to install TRAFFIX, a unique “TRAFFIX.KEY” file is required. Users should make sure they have a valid key before proceeding with the installation process. These keys will be e-mailed to users downloading the program, or they will be included on the distribution media.
Multiple versions of the program can co-exist and run, provided each is in its own directory. So if you have a copy of Traffix 7.5 installed, it can remain as long as you install Traffix 7.6 in a different directory. Keep in mind however that TRAFFIX data files are not designed to be backwardly compatible.
