You DE-activate on 'computer a' and install and activate with your serial number on 'computer b'

-OR... Go to https://www.adobe.com/about-adobe/contact.html

-click on the Chat bot on the bottom right hand corner of the first screen

--the chat bot is the circle with a funny looking box with 3 dots inside

-click on Downloading or Installing, then type Agent

Do NOT let the support agent tell you to come to the forums for help... no user in a public forum has access to Adobe's internal links, you MUST obtain the program and update links from Adobe support

AND when you finally do have a download link, be sure to copy every file you download to an external drive (or 2 or 3) so you never have to hunt for download links if they are moved again... also make a text file containing ALL of your serial numbers and copy that file as well
