Sorry, at this time, floating and network licensing is not offered for any of our products. The license must be activated for each computer that the plugin is installed on.
However, all of our products allow your license to be easily removed from one computer and re-activated on another computer. This allows licenses to be easily shared among multiple users / systems.
Simply open the License Manager for the extension (found in the Extensions->Product Name) menu and then click 'Remove License'. This will 'release' the license so it can be activated on another computer.
