Downloading Acrobat Pro XI

[DrDea]

I have purchased a new computer and would like to install the Acrobat Pro XI from my old computer onto the new one. When I purchased Pro XI (back in 2013), I had a different email that I can no longer access. I opened a new Adobe account with my newer email, so my Adobe account does not list the Pro XI among my products.  I have the serial number. Is there a way to install the Pro XI on this new machine?

Are you able to access the old computer?

To deactivate Acrobat XI/X, launch the app, choose Help > Deactivate.

Once it is deactivated, you can install on another computer with your new account.

I will reply to myself! I contacted Adobe through a chat. They asked for the serial number and sent me a link to get the installation done. Very easy! I should have started there! Thanks to all who provided advice.

Glad to hear you have found a solution.

When you have a download, ALWAYS copy it to at least one external device
-a usb flash drive or hard drive, or write to a CD or DVD
-plus a text file containing your serial number
