Setting a Runtime License

LEADTOOLS requires a runtime license file and a developer key. Below is a description on how to obtain a LEADTOOLS runtime license file and a developer key.

Temporary Licensing

Obtain a temporary runtime license file and a developer key to evaluate all features.

To do so, download the latest build of LEADTOOLS and have a temporary runtime license and developer key emailed to you by registering at the following link:

https://www.leadtools.com/downloads

Permanent Licensing

To obtain a permanent runtime license file and developer key, perform the following steps:

  1. Purchase a development license for the LEADTOOLS product(s) that includes the desired feature(s). Upon purchasing a LEADTOOLS development license, a temporary runtime license file and developer key will be sent to you, so you may continue to develop while a deployment license is put into place. If you have purchased a LEADTOOLS development license, but are not able to develop because you have not received a developer key and license file, contact sales@leadtools.com.

  2. Complete and submit the Deployment License Application Form (DLA) to obtain a quote to purchase deployment licenses. After submitting the form, licensing@leadtools.com may contact you for additional information to finalize the deployment license agreement.

  3. Next, purchase any necessary deployment licenses, and if applicable, complete and sign a Commercial Deployment License. The signed document can be scanned as a PDF file and sent to licensing@leadtools.com, or sent via fax to +1-704-372-8139. To obtain a copy of the Commercial Distribution License for your specific needs, contact oemsales@leadtools.com.

  4. Finally, after licensing has received your Deployment License Application Form and, if applicable, the Commercial Deployment License, licensing will send the specific license file and developer key necessary to unlock the appropriate features. At this point, you can distribute your application per the deployment license agreement and, if applicable, the Commercial Deployment License.

Using a Runtime License File and a Developer Key

The above instructions apply to temporary evaluation and permanent LEADTOOLS license files and developer keys. After receiving the developer key and license file, use the license function corresponding to your development environment and target platform.

Medical, Document, and Imaging Products

The Media Raster feature known as DVD Burner in the Multimedia toolkits is unlocked with any of the above methods if it is included in your LEADTOOLS runtime license and is available for the target platform.

Multimedia Products

Unlike LEADTOOLS Medical, Document, and Imaging products, LEADTOOLS Multimedia products use license keys instead of a runtime license file/developer key combination to unlock specific multimedia DirectShow and Media Foundation filters. These keys will be sent to you by licensing@leadtools.com after appropriate deployment licensing is in place. Until then, the LEADTOOLS DirectShow and Media Foundation filters are available in evaluation mode. For more information, refer to LEAD DirectShow and Media Foundation Evaluation Mechanism.
