I did one test where if you log into the Adobe Creative Cloud Desktop link with an Adobe ID you can install another Adobe program which is fantastic. Does IT have to enter a key for the user to register it or does it use the same license key? Example: I installed Adobe Acrobat Pro 11, Photoshop & InDesign but I have a user that wants to add Illustrator. Does a user have to enter a key every time they logoff Creative Cloud?
We would like to inform you that if you have got a Creative Cloud subscription, you would be able to install all the software which would include in it.
No extra activation code/ serial # is required. It works with your Adobe ID.
