Differences Between Alternate License and Original License

This information is included so that the customer clearly understands what type of license they are acquiring and what features they can expect based on the chosen option.

Alternate License: is a non-original, one-time payment license with no monthly or annual subscriptions. It allows functional use of the program to diagnose, review, maintain, and work with the available tools from the device where it is installed. It does not include official updates, cloud functions, or linking to personal manufacturer accounts. Linking accounts, manual updating, or modifying the program may affect activation and require additional technical assistance at a cost.

Original License: is the official manufacturer's option. It includes access to full features according to the contracted plan, an official account, online services, updates, and official support. Its cost is usually higher and it typically operates under monthly or annual plans with an expiration date.

For business, corporate, governmental, or institutional use, Luctecno recommends original licenses, as they are the appropriate choice for compliance with best practices, audits, formal support, and more demanding professional needs.

Note: These licenses are tied to the device where they are installed and are not transferable.
