I've purchased Acrobat XI already and received my order number, however the installation process is telling me I need a serial number/code. This was not included in the email sent to me when I purchased the application. I'm finishing some college apps and desperately need to use Acrobat, and so I'd be especially appreciative if someone were to tell me how to get my serial number/code.
Did you buy a subscription. If so there is NO serial number. Just sign in with the SAME Adobe ID and, if your subscription is processed (check account details), you will have access.
