You can install and activate (purchased) perpetual software two computers of the same platform (mac or pc), as long as you only use it on one at at a time.
If you will not ever be using the software on the first computer anymore, deactivate the license on that computer- how to deactivate software. This allows it to be installed on another computer at any .
If you no longer have access to the computer, and your software is still supported, you can ask Adobe Support to help you deactivate the software. Have your serial number or Adobe ID ready, and then contact us.
