The software is available on the official website, and it's mentioned that it supports Windows and Mac, but nothing about the versions of these two operating systems, because we know there are many versions released. If you have an account on the website, log-in to the Member's area and then check to see what are the supported versions of Windows and Mac that can be used to install PANTONE Color Manager.
