Software License

Starting from version 2.1.0, Mech-Mind uses Sentinel LDK as its software license system. This license system supports the hardware license (HL) and software license (SL) encryption methods, and provides the permanent and temporary licenses.

Mech-Mind will determine the appropriate encryption method and assign a validity period based on your actual needs.

  • HL key: A USB-based hardware key that supports writing licenses for different software by using a product key.

  • SL key: A virtual key that supports writing licenses for different software by using a product key.

  • Permanent license: A license that allows for permanent use.

  • Temporary license: A license with a specified expiration date. You can update the license to extend the expiration date.

The following sections introduce how to obtain and manage software licenses, as well as troubleshoot common licensing issues.

Obtain Software Licenses

  • If you need to use an SL key, please contact Mech-Mind sales team to obtain a product key. Mech-Mind will send the product key to you via email, as shown below. The email will also include a link to the Entitlement Management System for activating and updating the license.

email example

  • If you need to use an HL key, please contact Mech-Mind sales team. Mech-Mind will deliver the HL key either with the product, by mail, or through on-site delivery. The license in the HL key is activated before delivery. To use the HL key, plug it into the USB port of the IPC.

  • You must download the Sentinel LDK encryption driver and install it on the IPC before you use an HL key or SL key. If you have installed Mech-DLK, the encryption driver will be automatically installed and you do not need to install it again.

  • When you are using an SL key, after you obtain the product key, you must activate the license to obtain software authorization.

Manage Software Licenses

You can refer to the following instructions for further operations.

  • If you are using Sentinel LDK for the first time, you must activate the license.

After you perform license activation or update, you can check the license to confirm whether the license is activated or updated.
