I have a copy of cs3, which i have upgraded to cs4. I have got a new compter and tried to install cs4. Enterd the prodkey for cs4. I (think) i have the right code. But its for a suite, and i only need flash moved over and its only the flash thats been upgraded. Iv tried entering the suite key and it hasnt worked. Any suggestions. I want to upgrade to cs5. But if cs4 isnt registered on this machine im assuming it will ask for the cs4 product key, then the cs3? Or if im upgrading to cs5 will it only ask for the cs4 key. Even though its an upgrade key! Sorry alot of questions there. Hope it all made sense!
