You can install Final Draft 9 / 8 on as many computers as you want. Two of these can be activated at a given time. You can activate two Macs, two PCs or one of each -- it doesn't matter.
If you have more than two computers on which you'd like to run Final Draft, you can either deactivate one computer and move the activation to another, which is 100% free (for more information on deactivating, click HERE) or you can purchase additional activations for $119.95 each. Note that additional activations must be used only by the registered owner only on computers he or she owns and operates.
Please call our sales line, 800-231-4055, if you are interested in purchasing an additional activation.
