The second control PC is in office network, but we have created an route via router to the factory network. We have two separate networks on our plant, one for normal office, and one for factory automation.
Only diffrence is that the new client PC is not in the same network. When i start runtime, the project opens up, and after 30 seconds, it close, and got the message: 'Software protection failure, No key found or no license available from network' The second PC is configured the same as the first PC, witch will work correctly. Now i have updated the USB key, so in the key update tool is the following information: 1 full license 2 control clients Software version V7.20 + SP2 Now on second PC, i have installed runtime, and configured all settings. On our plant we have an server license, and 1 control license for client.
