  The License Parameters table provides information about your license. The following information about your ABBYY FineReader Engine 12 license is available:

  * Functionality subset of the license (Developer or Runtime, and any license limitations, e.g., Trial).
  * Type of protection (software, hardware, or online protection).
  * ABBYY FineReader Engine 12 serial number.
  * Customer Project ID.
  * License expiration date.
  * Performance limitation: CPU core limit (the number of CPU cores which can be used for recognition), minimum number of CPU cores which can be used on a station, performance limit (e.g., characters per second).
  * Environment limitation: usage in a network, on virtual machines, on Amazon EC2 and Microsoft Azure.
  * List of features that are allowed by your license: text types, export formats, additional modules, etc. (see the [Modules](/fine-reader/engine/licensing/modules) section).

  You can also access all these license parameters via the API. Use properties and methods of the [License](/fine-reader/engine/api-reference/license-related-objects/license) object.

  ## Runtime license emulation

  You can use your Developer's license in the Runtime emulated mode. This allows you to test your application which uses the ABBYY FineReader Engine 12 library.

  To try emulation, select Emulated mode for license parameters. To change settings, click Change and in the License Emulation Settings dialog box that appears, select modules that will be enabled for your Runtime License (you can select only those modules which are supported by your Developer License). If some modules are not used for your Runtime License, disable them.
