I am trying to install CS5.5 on a new Mac.
I have confirmed the serial number with what is on my account. When I enter the number (confirming it is correct) - I get a message that the serial number is invalid for the product.
When I purchased CS5.5 (in 2010), I already had CS4 - so this serial number was for an upgrade. Could this be the problem?
I don't see a way with the downloads available to mimic a CS4 install followed by an upgrade to CS5.5.
Suggestions???
