   * Click on the link for checkout page for desired edition. This will redirect you to the online payment system web page.
     
    .. note:: Although it is called payment system, no credit card is required for free Community Edition.

2. Activate *ogamma* Visual Logger for OPC using its web configuration GUI which is by default available at http://localhost:4880. All license related activities can be done via ``License Information`` dialog window, opened by menu ``License/Status``.

  .. note:: You need first login in order to access the menu ``License``. Before starting of the application very first time, default login credentials should be set by using environment variables ``OVL_USER_ID`` and ``OVL_USER_PASSWORD``. If environment variables are not defined, then values ``admin`` / ``password`` will be used. After first login using these credentials, the application will display warning message and will force password change.

  In case if the machine where *ogamma* Visual Logger for OPC is running has access to the Internet, activation can be done in online mode. If that machine has no access to the Internet, use offline activation mode. Steps to activate for these 2 cases are described in subsections below.

  * 2.1. Online activation.
 
    Screenshot below shows ``License Information`` dialog window to activate in on-line mode. Note that checkbox ``Activate off-line`` is off. 

    .. image:: images/activate-online.png

    * In the e-mail received in the previous step, find activation code (it is started by letters ``VL``) and copy it into clipboard.
    * Paste activation code into the ``Activation Code`` field. After entering the value, call to the backend is made, after that appearance / visibility of GUI controls might change. For example, if the activation key was already used before, label on the button ``Activate`` will change to ``Reactivate``.
    * In the ``Password`` field enter password, which will be used by online License Portal to access your activation code in the future, as well as that password is required to de-activate license and activate in other computer when such transfer is required. 
    * In the next field confirm password.
    * Enter email address, which will be used by online License Portal to restore your password in case if you forgot it.
    * Click on the ``Activate`` button to complete activation. Dialog window will popup asking to accept license terms. 
    * After accepting license terms, *ogamma* Visual Logger for OPC will connect to the online licensing server and will be activated in case of success. After completion, notification message will appear displaying result of activation.
    * Refresh web page to display content which was not displayed in non-licensed state.

    .. note:: License file `ogamma-logger.cdm` is expected to be located always in the  folder ``./data/[InstanceId]/`` (relative to the work directory) where ``[InstanceId]`` is unique identifier of the applicaion instance. The folder is created at the very first startup of the application. If you change location of the application installation folder or work directory, make sure to move license file accordingly too.

Upload Annual Maintenance and Upgrades License.
==================================================

Starting from version 2.2.0 valid ``Annual Maintenance and Upgrades License`` is required. For details about this license please refer to this section:  :ref:`amul`

After obtaining the AMU license file from the vendor, to install it, open the dialog window by menu command ``License / Status``, and click on the button ``Upload AMU License file``. A new dialog window will be opened. Select the license file from the filesystem, and click on the button ``Upload``. 

To view the current status of the AMU License, open the ``License Information`` dialog window by menu command ``License / Status``. The current status of the AMU License and its expiration date will be displayed in the section ``Annual Maintenance and Upgrades License``.

One or more AMU license files can be uploaded. Also, if the same file is uploaded by mistake multiple times, that does not cause a problem. After uploading the AMUL file neither restart nor connection to the Internet is required to apply it. 

.. note:: AMU licenses are associated with the original license. You can figure out what the original license the AMU License file is associated with by its file name. The format of the file name is ``amu-XXXX-YYYYYYYYYYYYYYYY.lic``, where ``XXXX`` is the last 4 letters of the original license activation code.
