RadarOpus only ever charged once for an update in September 2019 (version 2.2).
If you purchased a new program AFTER 2019 you will not have been charged for the update.
We strongly recommend to keep the program updated, as the updates always include key security and stability features beyond normal improvements and bug fixing.
If you have an old RadarOpus version (2.1 or below) then you only need to pay once to get the latest version (containing all the updates made over the years). The longer you wait to update, the more expensive it becomes (because you get added value every year with newer versions) so we strongly recommend you to update now. To do this please contact your local representative .
If you try to install the latest RadarOpus version but you do not have the permission on your license (because you have not paid for the update from an old RadarOpus version) your program will not start.
