It does not tell you this on the CD package when you buy it, but I just talked to the CSR about this problem. If you buy the CD, it has the option to download both platforms--on a Mac or a PC. They offer the Download option sort of as a "complimentary service".
Also---for the Download, it is ONLY available (for CD purchasers) on one platform--EITHER a Mac or Windows PC. For example, You cannot chose Mac and then also use the Download feature for the Windows version. You would need to use the CD to get the Windows version at that point.
