You cannot upgrade from a suite to a single application that is part of the suite.
It's all or nothing.
Adobe's reasoning is that you already obtained a substantial price benefit when you bought the whole suite.
So, i make mistake. How can i have money back from buying Photoshop cs6? Can i upgrade my Production premium cs 5.5 to any cs6 suite? Even i don't have indesign in my suite?
You can always get a refund within the first 30 days after yiur purchase.
