MARIN software is secured with MARIN’s Simple License Library (SLL) licensing. There are two kinds of SLL licenses, node locked licenses and floating licenses.

A node locked license is a license that can be used on one PC. It is created for that PC and will not work on another PC. Floating licenses are licenses that are installed on a license server and that can be used by PCs that have network access to that license server. Floating licenses are used to share a limited amount of licenses among a larger group of users.

This document describes how to use node locked licenses on Windows.

To be able to create a license for you, MARIN needs the host ID of your PC.

MARIN SLL licenses usually are named after the program they are for and always have the extension ".sll". You need to store the license in one of the default locations mentioned below. Additionally you need to store a configuration file, called sll_client.cfg, there. That file is used to easily switch between a node locked and a floating license.

Obtaining the host ID

  1. Open a Command Prompt. In Windows 10 you can do this by clicking the Start button and typing "cmd". The Command Prompt Desktop app will appear as Best match. You can either click it or just press Enter to start the Command Prompt.

  2. In the Command Prompt type

    ipconfig /all > C:\ipconfig.txt

    If you get the error message "Access is denied" it means you do not have sufficient privileges to write in the specified directory. Choose a directory where you have write access.

  3. The output of the ipconfig command will be written to the ipconfig.txt file, in the directory that you specified.
  4. E-mail the ipconfig.txt to so MARIN can create a license file for you. In the e-mail, please specify the program name and version number that you need a license for.

Storing the license file

MARIN SLL license files and/or client configuration files can be stored in one of the following default locations on Windows:
C:\Program Files\marin\licenses
C:\Program Files (x86)\marin\licenses

These locations do not exist on your PC by default. You need to create one of them if they do not exist yet. 

C:\ProgramData is an invisible folder.

MARIN SLL license files and/or client configuration files can be stored in other locations on your PC. If you do so, please make sure that location is stored in environment variable MARIN_LICENSE_PATHS. Several license locations can be stored in this environment variable. They have to be separated with a semicolon(";"). For more information on how to set this variable in Windows, please read Adding the MARIN_LICENSE_PATHS environment variable.

Please do not add the MARIN_LICENSE_PATH environment variable if the license and/or the client configuration file is in one of the default locations

Storing the configuration file sll_client.cfg

MARIN SLL Licensing needs a configuration file, sll_client.cfg. This file enables the user to switch between a node locked license and a floating license easily. The contents of this file, for a node locked license is:
    <local enabled="true" />
    <server enabled="false" host="yourlicenseserver.server.local" port="27005" />

Put the sll_client.cfg file in the same directory as the license file so it can be found by the application.
