I cannot readily find instructions to transfer/download my old Professional DC license to my new computer. I have attempted the instructions of the Creative Cloud apps downloads to no avail; it shows options for downloading Adobe Acrobat trial but nothing for transfer of my old license purchase for the old computer to this new computer. I have downloaded a few files to not get what I wanted.
I can provide any details of the previous purchase.
If you purchased a subscription you just need to log out on the old computer and then install the same version and log in on the new one.
