The license agreements for all of Synergy Creations' software, if licensed (registered), means that if you are permanently transferring a computer to another party, you should remove ("unlicense") your license from the computer you are transferring. If you transfer the license with the old computer, you must purchase a new license for your new computer if you wish to continue using the software.
This page contains small programs which can be used to remove licenses for Periodic Table, Alchemist's Challenge, ConverTable Units, or ChemDuet on Mac OS X systems. Simply download the program you need to the Mac you are transferring, unzip the downloaded file, and double-click it to run. You will be asked to confirm that you want to remove the license.
Please note that these are not uninstallers. To uninstall our Mac software, simply drag the program's icon to the trash (they are generally stored in your Applications folder). Uninstalling does not remove the licenses. You only need to remove the licenses if you are transferring the computer.
