You need a license to use any piece of Chemaxon software. This can be granted to you by either a file or a key. License file is a document you must make available for the Chemaxon software to valide your usage rights, license key is a unique identifier checked online to grant you rights for using the Chemaxon software. Both solutions can be used independently or together. You can provide the needed settings either with our LicenseManager tool (can be downloaded with Marvin or JChem package), or with manual setup.
The license file can be placed to its default location, or you have to set where to look for the license.
The default location is
<chemaxon_home> can be set by the
CHEMAXON_HOME environment variable. Its default value is
<user_home>/chemaxon on Windows and
<user_home>/.chemaxon on Unix-like systems.
<user_home> means the home folder of the user that executes the Chemaxon application.
License file can also be set by
CHEMAXON_LICENSE_URL environment variable, or by the
chemaxon.license.url JVM parameter.
License key can be set by the
CHEMAXON_LICENSE_SERVER_KEY environment variable, or by the
chemaxon.license.server.key JVM parameter, or by editing the file:
<chemaxon_home>/license-manager.properties. (The name
<chemaxon_home> refers to the folder described above.)
Please note that Marvin JS license installation is different, the installation guide will be sent to you together with the license.
