A support person told me that I only need to buy a CS6-upgrade for Windows and would be able to install it on a Windows PC by entering my CS4-Mac-serial number, is that true?
I'd like to know that before I spend a lot of money for the upgrade.
By the way, I don't necessarily need the CS6 version but I'm about to buy the upgrade because I heard that cross-grading works only with CS6. Can you help me?
