Thank you for your response.
My question wasn't clear. In a computer A with user A, CS was installed. For this computer A and user A I install CC.
Can I use the licence CS on a computer B with use B?
Thank you for your response,
You can install CC or CS from your subscription as per your convenience.
You have Creative Cloud for Team, so if user A uses CS version & user B can use CC. The choice is of the user.
Do feel free to inquire further.
