Chapter 3Installation Troubleshooting

Troubleshooting TableReview this table if you have problems installing any HEXTRAN application. If you cannot correct the problem, contact your local SIMSCI Technical Support Center (see page xi).

Table 3-1: Installation Problems and Solutions

Problem You cannot attach the security to the parallel port. Some computers do not have enough space around the parallel port to allow you to insert the security device and/or chips.

Solution Attach a short ribbon-extender (less than two feet long) to the security device. This moves the security device beyond the obstruction.

Problem Corrupt files.One or more files appear to be corrupted based on an unusual file size or run-time message.

Solutions Run CHKDSK to verify the drive.

Remove the current installation.

Reinstall the programs from scratch.

Problem Invalid path of access failures: You received messages that files could not be copied and that the installation failed.

Solutions If you are installing to a network, ensure that you have adequate read/write access privileges.

Ensure that you have enough disk space in the specified directory.


Problem You have problems using the printer with the DS1410D SIMSCI security. The following printers have problems working with the DS1410D local hardware security button holder:

HP Laser Jet 4M Plus, 4P, and 4L: The Auto Power Down feature may cause communication failure with DS1410D.

HP Laser Jet 5L: The driver fails to install when the hardware security device is connected.

HP Desk Jet 540 and 550C: Using the HP-supplied driver may cause communication failure with the DS1410D when the driver determines the type of cartridge that is installed.

Canon Printer: The Auto Power Down feature may cause communication failure with DS1410D.

Epson 300LX: Communication to the DS1410D may cause the printer to interrupt printing.

Solutions HP Desk Jet 540 & 550C only Using the HPVCNFIG.EXE utility, configure the driver to not check for the type of printer cartridge in the printer. This enables the HP driver to function correctly with the DS1410D.

HP Laser Jet 5L onlyRemove the security device before installing the driver.


3-2 Installation Troubleshooting

Problem Security chip missing errors.

Solutions The security device must be the first item in parallel port.

Make sure that the security installation has been completed correctly and that you have the security device listed in the installation instructions. Make sure that the security device is firmly inserted into the parallel port.

Check the 25 connector pins on the security device for damage.

If a printer is attached, make sure it is turned on.

Some laptop computers do not put out enough voltage to the parallel port to return an answer to the program. Test this by attaching a printer, turning it on, and executing the program. If it works with a printer attached, you can use that as a solution. You can also try moving the program to another computer or attaching just a cable at least two feet long to the printer side of the security device (no printer).If nothing works, contact Technical Support for a special battery adapter to increase voltage directly to the security device.

Make sure only similar security devices are piggybacked.

Problem The program is installed on a system running Windows NT. When you run the program, it produces errors relating to security.

Solution Ensure that the person who installed the program has system administration rights/privileges.
