You can install it on the other computer, however once you do you will need to go on the magix website and deactivate the current computer as you can only use it on one computer at a time. It should be under my products where your product serial will also be. Once you download your software on the new computer it will ask for your serial number and the number wont work unless it has been deactivated from the other computer so you may use it on your new one. You can also try to just install software on your new computer and just enter the serial to see if it works if not you will have to go to the website and deactivate its from the other computer.
