In Creative Suite 6 for MAC--why do I always have to insert my serial number?

[paulevy]

Everytime I try Photoshop I have to enter my serial number--not so with the other apps--how can I avoid this?  The window says "Your Trial Has Expired" and asks me to join Creative Cloud which I don't want to do!  So I click on "License this software" and enter the serial number and go to Photoshop--but every time??????????  PLEASE NOTE THIS IS FOR MAC SOFTWARE--NOT WINDOWS.  I cannot navigate to c:\Program Files X(86)\Common Files\Adobe\AdobePCD as suggested in an earlier reply.

Could you update your Photoshop to the latest version and then check.
