How do I activate my Adobe InDesign CS6 Subscription Edition (month-to-month) plan
Have you alreday purchased a subscription?
After installing the software, once you sign-in with your adobe ID, it'll activate automatically.
Yes purchased a 1 month subscription today
when i go to open CS6 it asks for a serial no.
At the bottom of the serial number screen, there is a "License this software" link. Click that link and then follow the on-screen instructions. They should get you started.
