Installing Licenses to Desktops

Note: Documentation for installing license files issued for versions prior to 5.0 can be found here.

This document describes the ways of installing licenses to PC i.e. desktop applications. This way the license is installed for the current user only.
For installing licenses on servers, please refer to this document instead.

The possible ways of installing licenses to desktops:

1. Install with GUI (recommended)
2. Using system variables:
   The location of the license file can be set with:
   • CHEMAXON_LICENSE_URL environment variable (help on setting environment variables)
   • chemaxon.license.url Java system property
   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 from the user's home directory will not be read unless the special word "default" is given.
   Example: -Dchemaxon.license.url="C:\ChemAxon\license2009.cxl;C:\ChemAxon\license2010.cxl;default"
3. 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)
4. Command line install:
   Launch the license shell script (Unix) or license.bat batch file (Windows).
   Type license -h for the list of available options.
5. Using API:
   chemaxon.license.LicenseManager.setLicenseFile(String path)
chemaxon.license.LicenseManager.setLicense(String s)

Launching ChemAxon License Manager GUI (CLM)

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 CLM in any package.
• Launch using the license shell script (Unix) or license.bat batch file (Windows).

Steps of installing the licenses

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.
