Launching ChemAxon License Manager GUI

ChemAxon License Manager is a central place where you can manage the licenses of all ChemAxon products. Three basic ways of launching:

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

  • The Start menu on Windows: Start->Programs->ChemAxon contains several packages.
    You can find the same Chemaxon License Manager in any package.

The licenses are usually stored in the license.cxl file which you receive from ChemAxon.
You don't need to open or edit the content of this file, just simply save it to an arbitrary location of your file system.

  • Click on the Browse... button

  • Select the location where you have saved your license.cxl file.

  • Press the Install button

  • Installing licenses is complete, you will see a license overview where you can see the installed licenses.

You can overview your licenses any time by selecting the "License overview" panel.

Alternative methods for installing the licenses

  1. Using system variables:
    The location of the license file can be set with:

    From version 5.3.2 it is possible to define multiple license files of arbitrary locations. The separator character is ";".
    In case license files are set this way, the license files will be read from all locations defined by the environment variable, the Java system property and from the user's home directory.
    Example: -Dchemaxon.license.url="C:\ChemAxon\license2009.cxl;C:\ChemAxon\license2010.cxl"

  2. Manual install:
    The license file must be stored in the .chemaxon (Unix) or chemaxon (Windows) sub-directory of the user's home directory. The following locations are accepted:

    • (.)chemaxon/license.cxl (the license file name is fix)

    • (.)chemaxon/licenses/*.cxl (from version 5.3.2 only - the license file can have arbitrary name, the extension is fix)

  3. Using API:
    chemaxon.license.LicenseManager.setLicenseFile(String path)
    chemaxon.license.LicenseManager.setLicense(String s)
