Camsoft’s USB dongle key security uses older RockUSB drivers.  On occasion, the driver that the Camsoft installation installs, gets updated by windows automatically or by the user unintentionally.  The newer RockeyUSB4 and Rockey4 drivers that windows installs, can cause problems for the software security feature.   Sometimes, the new drivers do work with the software and sometimes on some Windows systems, they fail with our software.  The exact cause is undetermined.  The solution is to remove the new drivers and make sure that only the driver which is installed by Camsoft’s installation is the one being used.

Begin by launching the Windows Device Manager applet.

Once the windows hardware wizard finishes, the LED on the dongle should be lit a solid green.  Launch CNC Professional to confirm that the security key is functioning properly.
