License Activation
##################

The Tetra4D Enrich licensing system makes it possible to activate your license without contacting
Tetra4D support.

In order to adapt to various situations, Tetra4D Enrich provides different ways to activate a license on
a computer:

* Online activation (computer connected to the Internet)

  * Activation can be performed

   - From the top menu Tetra4D Enrich > Request license dialog box,

   - From the license manager, accessible in the top menu: Tetra4D Converter > License manager.

   .. note::

      The license manager is only accessible in the Tetra4D Converter top menu.

* Offline activation (computer not connected to the Internet)

   * Activation can be performed from the license manager, accessible in the top menu: Tetra4D Converter > License manager. 
  
.. important::

   We have noticed an ADOBE Acrobat Pro issue that may affect the Tetra4D licensing mechanism. If you are installing TETRA4D Enrich for the first time, please verify in Acrobat Pro the below setting and make it sure it is disabled:
      
      Edit -> Preferences -> Security (Enhanced) -> "Enable Protected Mode" in the "Sandbox protection" section.

   Then restart Acrobat.

License activation: Online
==========================

To access the online activation dialog:

* Start Acrobat Pro, and select I already have a serial number in the Tetra4D Enrich status dialog (this dialog will pop-up if tetra4D Enrich is running in trial mode).
