7.2 Problems at station start
7.2.1 DEMO – missing HW Keylock
The Rockey (or Sentinel) protective key (dongle)
must be plugged in either a parallel or USB
port and its driver must be properly installed.
Several problems may cause this error
message:
1. Your protective key may not be properly
installed. In the Control Panel select the System
icon, access the
Device Manager tab and look for
"Universal Serial Bus Controllers" - "Feitian
Rockey4 USB" item (or "Feitian Rockey4" for
printer port hardlock). It can be also directly in
the root folder. If it is not there:
Solution:
By using the ROCKINST.EXE program in the
HW_DRIVERS\ROCKEY subdirectory of the Clarity
workstation.
2. You might have inserted the USB token before
installing the Clarity station. Normally Clarity
station installs proper drivers. In this case, MS
Windows probably automatically installed
incorrect drivers.
Solution:
In Windows XP it is recommended to use the
System Restore (menu Start – Help and
Support) to uninstall the incorrect drivers.
In older versions of MS Windows it is
necessary to uninstall the incorrect drivers and
manually install the correct one as described
above.
