If you want to transfer your registration code to another computer, we can reset the registration code for you and then you can register the program on another computer again. Please send your order number and billing email address to the support team. This process will only work with computers using the same operating system (either two Windows PCs or two Macs). If you want to use the same program on a computer with a different operating system, you'll need to purchase a second registration key for the other OS.
