The software available for download can be used indefinitely once installed. However, to access future updates, an active subscription is required. If your subscription expires, you can continue to use the existing version of the software, but you will need to purchase a new account if you wish to receive updates. This means that while the core functionality remains available, ongoing improvements and new features will only be accessible with a current subscription. Thus, maintaining an active subscription is essential for users who want to stay up-to-date with the latest enhancements and support.
