License Server Configuration

    {info} License server configuration is only available from version 19.26.

    This document describes how to use Chemaxon's Central License Server (instead of a local license file).

    Get license key

    You can find your personal license key in the following link (after logging in with the Chemaxon account):

    https://accounts.chemaxon.com/licenses

    (Only available if you have an active license on the license server.)

    {info} Your license key must be protected. In case it is compromised, a new key should be requested from Chemaxon.

    Install with GUI (recommended)

    You can use Chemaxon License Manager GUI. It is a simple application where you can manage the licenses of all Chemaxon products.

    • Start the License Manager:

      • Choose "Licenses..." from the Help menu of any Chemaxon desktop application.

      • Or find the License Manager among your installed applications (e.g., on Windows: Start menu → Programs → Chemaxon).

    • Under License server configuration , you can set your personal license key. You can optionally test the configuration here.

    • Click on Apply to start using the central license server.

    After successful configuration, available licenses are automatically checked on the license server when you start an application that requires a license. For this check, an active internet connection is required. After a successful license check, the specific application can be used for 15 days offline. (If you have troubles with the license check process, check your proxy settings and ensure that https://license.chemaxon.com can be accessed.)

    Manual installation by editing properties file

    License key and license server URL can also be set by editing the file <chemaxon_home>/license-manager.properties. This file must contain the following entries:

    server=https\://license.chemaxon.com
    license-key=<your_license_key>

    Using system variables

    License key and license server URL can be set with the following environment variables (help on setting environment variables):

    CHEMAXON_LICENSE_SERVER_KEY

    CHEMAXON_LICENSE_SERVER_URL (optional if not the default license server is used)

    Using JVM parameters

    License key and license server URL can be set with the follwoing JVM parameters:

    • chemaxon.license.server.key
    • chemaxon.license.server.url (optional, if not set, the default license server url is used)

    {info} Please note that when you install your licenses with a license key through a license server, no license file (license.cxl) is generated through the installation process, the installation of these two license types is independent from each other.
