Clarisse licensing system can work with a node locked license that is attached to a machine or a with a more flexible floating license system based on a client/server model. Our licensing policy lets users run an infinite number of Clarisse application instances on their computer once it has been granted with a valid license. Licenses are valid for all platforms and can either be temporary or permanent.

Licensing Isotropix Products

There are multiple ways to license our products. You can directly license our products using command-line arguments or using our dedicated tool Isotropix License Manager (LICMAN).

Command-Line Arguments


To set the location of your node-locked license, just add the following command-line argument -license_path. For example:

clarisse ... -license_path /path/to/my/license.key


This argument only works with applications that support node-locked licenses such as Clarisse. CNode, for example, doesn't support node-locked licenses.


To specify the network machine name or the host address hosting ILISE, just add the following the command-line argument -license_server. For example:

clarisse ... -license_server ILISE-SERVER

cnode ... -license_server


You can also specify ILISE port using the same command-line argument:

cnode ... -license_server ILISE-SERVER:40500

clarisse ... -license_server


Alternatively you can set the environment variable ILISE_SERVER to the host address and port running ILISE. Assuming the server is running on the IP address using the port 40000:

The Request Key is an identifier used by our licensing system to generate licenses for a specific machine. Please note that our licenses are bound to the machine that generated the request key. In other words, a license generated on a specific machine won't work on another one so make sure to generate the request key on the machine that will run the license. A Request Key will typically look like:


Request Key

Request Keys can be generated using Isotropix License Manager or using the tools provided here:


Request Keys are also unique per host and per session of the application generating the key. This means that each time a request key is generated on a computer a new one is generated. This is the expected behavior.
