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):
(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_URL (optional if not the default license server is used)
