You can install and activate (purchased) perpetual software two computers of the same type (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 time.
To load the software on another computer , download and install it as you did on the first computer. Then enter your serial number to activate it.
Here are the links you can download from if you do not have disks:
