This activation requires that your server can connect our external ngSurvey servers. If you need an offline activation contact our sales.

If you running ngSurvey on closed network you may uncheck the **Serial number** option and send us the License code, we will in return send you a code that you can copy / paste to activate your copy without network connections.
