What version of Photoshop. I believe all newer versions of Photoshop require an Internet connection to an Adobe activation server to activate Photoshop the server will write credentials onto your machine. I don't think Photoshop can be activated offline. Registration will also be done during activation if not already done, Versions of Photoshop prior to CC required a serial number to be entered by you the user. Photoshop CC requires you to sign in to the cloud to activate Photoshop CC. Your user ID account must have a subscription for activation to work.

I have booked marked your link never knew offline activation was posible. Thanks...
That kind of rules out using the cloud if a machine is never online. Is this posible with Adobe Creative Cloud products?
