Issue
When starting SIGNAL, a pop-up window declares "Sorry this program has not been enabled". But the security plug is installed in the computer’s parallel printer port (LPT1).
Environment
Windows XP with SP2
Cause
The HASP security plug driver that is included with the Signal-XP software is not compatible with Windows XP-sp2.
Resolution
Follow these steps:
- Ensure that the serial number on the security plug matches the serial number on the Installation Diskette #1. The first 4 digits of the serial number are a data code and DO NOT need to match. The last 4 digits MUST match. This applies to all versions of SIGNAL.
- If it’s SIGNAL for Windows XP (version 5.0), the drivers for the security plug need to be updated. See Technical Alert TA06-03 for details in updating the drivers.
- If it’s SIGNAL for Windows 95/98 (version 4.4.1 or earlier), try the following:
- Disconnect any printer.
- Modify LPT1, in Windows and/or the computer’s BIOS, and make it bi-directional.
- Use the Plug Testing utility program (16Bit Plugtest.zip) available from The Exchange Download Center to validate the security plug. If it’s defective, a new security plug can be ordered.
