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/license-server

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

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 30 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.)

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)
