This problem occurs when the software is not able to detect the key on the Parallel Port /USB Port of your system. This may be because the Key is not properly installed during installation for some reason.
If Leo Key is of hasp company then
Do the following Steps to install the Hasp Drivers:
This errors message will show two buttons "Retry" and "Cancel". Press the Cancel button first time. Shut down your computer, tighten the Leo Key properly. Restart the computer.
Now press the Start button, go to Run and type following commands:
- "C:\LeoStar\Leo Key\Cmdline\Hinstall.exe" /i and Press the OK Button.
- "C\LeoStar\Leo Key\HDD32.exe" Press the OK Button, then load the hasp driver by clicking the Yes Button. It will install the required files. Restart the computer and load the Software again.
If the message appears again after above mentioned steps, try to change its mode from the Integrated Peripherals section of BIOS Setting. You may try to change different Parallel Port modes from ECP to EPP or ECP+EPP and so on. This may probably solve the problem in your computer.
(To change Parallel Port Mode in the BIOS setting, reboot the system first. Press Del Key as soon as the system starts. It will Open your systems BIOS settings. Now Select Integrated Peripherals. Probably the last option in the INTEGRATED PERIPHERALS is 'Parallel Port Mode'. Now press '+' or '-' or if mouse works in the BIOS then change Parallel Port to 'EPP' if it is different from 'EPP'. Now Save BIOS Settings by Selecting Save Settings from it and restart the computer.)
If the message still appears then try installing the application on a different computer. If the application runs fine and do not give this error then this problem may be a hardware problem with your printer port.
