Howdo I install my present Photoshop software on my new computer?
Just like you did on your present computer - you run the installer. Just deactivate on your old system....
How do I deactivate my old system?
Open any application e.g. Photoshop and click Help > Deactivate.
You don't need to repeat that in any other apps since deactivating one app deactivates the entire suite.
