Updates with bug fixes or minor improvements are offered free of charge at regular intervals. You will be automatically notified when there is a free update when you start the software. In addition, you can also check for updates from within the program.
Upgrades with new functions and major changes are offered for a charge and are distributed as an independent, new program version. However, existing customers always receive a significant discount for such upgrades.
The purchase of upgrades is not mandatory. If you are satisfied with the previous range of functions, you can continue to work with your version without hesitation.
