Doug's advice is fine, but if you want to avoid using a command-line application, the issue is to be able to use it with i1Profiler for which you need a license from X-Rite. You should ask whoever you bought it from to provide the licensing information and enabling device, if any, so that you can call X-Rite and get the ownership transferred; this may need the original owner's cooperation. Otherwise you would need to buy a license for i1Profiler from X-Rite, or a license from
basICColor Print 5 to their Print 5 application, to be able to generate the profiles. Be advised, none of this software comes cheap, and from what I've seen, Argyll at least comes with usable documentation, compared with X-Rite's i1Profiler, which has none. basICColor comes with a manual also.
