Differences between alternative 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.

Alternative license: this is a non-original license, a one-time payment with no monthly or annual subscriptions. It allows the program to be used functionally to create, edit, save, and work on projects from the computer where it is installed. It does not include official updates, artificial intelligence features, cloud services, or linking to personal manufacturer accounts. Linking accounts, manually updating, or modifying the program may affect activation and require additional technical support at a cost.

Original license: this is the official manufacturer's option. It includes access to full features according to the contracted plan, an official account, online services, updates, AI features when available, 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 option to comply with best practices, audits, formal support, and more demanding professional needs.
