I installed Win 7 and figured activation would recognize MAC address and allow me to activate. Doesn't work. What can I do?
Going back a step.
Which Adobe product are you trying to install? Mac or Windows version of that product?
Are you trying to install on Win 7?
Is it a Creative Cloud product or the traditionally licensed version?
The activation is not based on the MAC address. It's genuine cryptography. If you reinstallyour OS, as a result the keys will be wiped and an activation be lost. Call support to reset activations server-side.
