The number of computers that can be activated is limited by the number of licenses you purchased. However the plugin can be installed on two computers, for example at office and at home. After it is deactivated in one computer, the license can be temporarily activated in another. If the Activation Key is only one, it will be possible to use only in one computer at the same time.
