Both the Bayes Server User Interface and the Bayes Server APIs operate in trial mode until a license key is activated.

User Interface

You can activate a license key in the user interface, by clicking the License button on the Start page, or by opening the About dialog.

Bayes Server API

You can activate a license key in the API by calling BayesServer.License.Validate("<license-key-goes-here>") at the start of your program, passing in your license key.


If you are using a distributed version of Bayes Server (e.g. running on Apache Spark) you will need to make sure this is called on each machine.
