Acrobat Serial Number Upgrade?
I am trying to install the Acrobat Pro XI that I purchased a few years ago on my new computer. My purchase was registered and I have the serial number from My Adobe account and used the installation link from my order history. But I am getting a "Serial Number Upgrade" error message that says "the serial number is valid but a qualifuying product wasn't found on the computer". How can that be when it's the same product and serial number listed in My Adobe account? Adobe chat wasn't helpful.
