I have just installed dw-2000 on Windows and am prompted the message "I/O Communication Error". What can I do to eliminate the prompt of this message?

Verify that each of the following factors have been implemented:

- the Hardware Key is properly connected in the LPT1 port

- any hardware (e.g., printer) that is connected to the other side of the Hardware Key is turned on

- the LPT1 port BIOS setting uses bi-directional

- the current version of the Rainbow Sentinel Driver is installed (Refer to one of the two procedures directly below)
