Licenses provided for free product evaluations and CUE programs are typically issued using the Node Trusted Storage license model.

In most respects, these free licenses behave exactly like purchased licenses.  However, a few subtle differences exist, as described below.

Offline activation is not supported for Trial or CUE program licenses.

Activation is done using the Online activation method.  

An active Internet connection is required at all times when accessing Lumerical tools.

Evaluate for Free

Floating license for Linux.

Linux operating systems only supports Floating licenses.

Activation on Virtual Machine.

Virtual machine activation is not available. Trial or CUE program licenses can only be activated on supported physical machines.

Proxy servers

Lumerical’s free trial or evaluation license must connect to the Internet to validate the license.

Some computer networks are configured so that individual computers access the internet via a proxy server. In these situations, the individual computers can not connect to the internet directly but instead send their requests through a designated proxy server.


Lumerical's software generally automatically detects the proxy server and works without the need for any additional action from the end-user. However, if you are having trouble with the license validation and your network uses a proxy server, you may need to manually configure your proxy server settings. A new window will appear if the automatic proxy detection fails, as shown the figure on the right.


Enter the proxy server IP address and Port number, then click OK.  If your proxy server requests a username and password, a second window will appear. Enter you username and password and click OK.

Manual proxy settings


Note: The standard windows OS proxy server settings can be configured using the settings in the "Internet Options" control panel. These settings are the same ones that are used by Internet Explorer. Normally if Internet Explorer is configured correctly then Lumerical's software will find the appropriate settings. If you are having trouble with the automatic proxy server settings, check your proxy server settings in the Tools - Internet Options - Connection - LAN settings menu of Internet Explorer.


Many computers use firewall software to improve security. Most firewalls are configured to allow all outgoing connections to the internet but to strictly control incoming connections. The trial license validation process only requires an outgoing connection to the internet, so normally no firewall configuration is required. If you are using very strict firewall settings you may have to add exceptions for to your firewall settings to allow outgoing connections. The best way to test whether your firewall is interfering with the license validation process is to temporarily disable it. If disabling the firewall allows the license validation process to complete, then you should re-enable the firewall and add the following firewall exceptions:


























*Engine / solver executables.
