Chapter 3Installation Troubleshooting

Troubleshooting Table

Review this table if you have problems installing any HEXTRANapplication. 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 beyondthe 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 andthat 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.


50/563-2 Installation Troubleshooting

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 onlyUsing 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 only

Remove the security device before installing the driver.




Problem Security chip missingerrors.

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 securitydevice.

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.
