Since the 8th of May, 2018, Microsoft has started the automatic rollout of version 1803 (feature update) of Windows 10 via Windows Update. Under this version, dongle licenses with all previous program versions 5.8 of conzept 16 are no longer executable.
We have now provided a new version with a workaround that enables it to run again. Version 5.8.09f is available for download in the Customer Center. To restore operability, the database server must be updated to 5.8.09f as a minimum. The dongle driver does not need to be reinstalled.
This workaround does not guarantee that dongle licenses will work with future Windows 10 updates, so we strongly recommend replacing dongles with internet-based licenses.
Update:
The dongle issue corrected for Windows 10 Update 1803 did not work under the 32-bit version of Windows 10. If it is a 32-bit system, the conzept 16 server version 5.8.09g must be installed.
