Installing a license — recommended methods

1. Use Chemaxon License Manager (GUI)

   • Launch LicenseManager (installed with Marvin/JChem packages or available in the installation folder).
   • Open “License server configuration” and paste your license key into the “License key” field; click Apply.
   • For license files, use the GUI to add/install the license.cxl/.dat file. LicenseManager will copy it to the standard location.

2. Manual installation (license file)

   • Place the license.cxl (or .dat) in the default location:
     • Windows: %USERPROFILE%\chemaxon\license.cxl (or %USERPROFILE%\chemaxon\licenses)
     • Unix-like: $HOME/.chemaxon/license.cxl (or $HOME/.chemaxon/licenses/)
   • Or set explicit path with CHEMAXON_LICENSE_URL environment variable or JVM property chemaxon.license.url.

3. Manual installation (license key)

   • Set the license key via environment variable or JVM property:
     • Environment: CHEMAXON_LICENSE_SERVER_KEY=<your_key>
     • JVM parameter: -Dchemaxon.license.server.key=<your_key>
   • Or edit <chemaxon_home>/license-manager.properties to include the key.
   • <chemaxon_home> defaults to %USERPROFILE%/chemaxon on Windows or $HOME/.chemaxon on Unix; can be set with CHEMAXON_HOME.
