Update license cache using dongle content on startup

When this checkbox is checked, TwinCAT 3 checks at every start of the Runtime whether the files on the hard disk correspond to those in the memory of the license dongle. If the dongle contains newer or additional files, they are automatically downloaded to the hard disk of the IPC ("cached"). This checkbox should always be checked.
