Other licenses are retrieved automatically in the same way as for online licenses.如果您有一个具有多个座位的HASP（在一个和同一个USB上有多个Seat许可证），请将加密狗插入本地网络中的任何PC。其他许可证将以与在线许可证相同的方式自动检索。
License broadcasting over the local network is not available for IG Channel and VR Channel USB Dongles.在本地网络上的许可证广播不适用于0_PHL和1_PHL USB加密狗。In case of multiple dongles used in one local network:如果在一个本地网络中使用多个加密狗：

Use the command line to run SDK Browser on the licensing host and set its IP and Port in the local network as command-line parameters. For example:使用命令行在许可主机上运行SDK浏览器，并将其在本地网络中的IP和端口设置为命令行参数。例如:命令行
browser.exe -licensing_host 192.168.1.1:4545After being started, SDK Browser on the host will wait for connection to Port 4545.启动后,主机上的SDK浏览器将等待连接到端口4545. - Run SDK Browser on the PC that is going to work under the license as follows: set the argument containing the parameters of the licensing host via Customize Run Options to run the application, or via Customize UnigineEditor Options to edit it.在将在许可证下工作的PC上运行SDK浏览器，如下所示：通过Customize Run Options设置包含许可主机参数的参数以运行应用程序，或通过Customize UnigineEditor Options对其进行编辑。
On the PC that has a dongle inserted (licensing host), SDK Browser shall be running. Other PCs that retrieve the license can do without SDK Browser and open the Editor or build directly.在插入了加密狗（许可主机）的PC上，SDK浏览器将运行。其他检索许可证的Pc可以在没有SDK浏览器的情况下直接打开编辑器或构建。
