Help: Sentinel SuperPro LPT Backup/Emulation for Industrial Software (PPI)

Hello everyone,

I am looking for help or advice regarding backup/emulation of a Sentinel SuperPro LPT dongle that protects my industrial software (PPI). My setup is quite old, but the software is still in daily use for important production tasks.

My configuration:

Software: PPI (industrial/printing workflow, works with .ppf files)

Dongle: Sentinel SuperPro, 25-pin LPT (parallel port), not USB

OS: Windows XP (I also have a backup XP system with native LPT1)

Dongle drivers: Sentinel Protection Installer 7.5.0

What I've tried so far:

sprodump.exe – dump stops at ~60%, produces a small, incomplete .dmp file

pva-dmp.exe / other classic LPT dumpers – same result, incomplete or error

Tried using giveio.sys and other port access tools – no difference

Tried using Toro Dongle Monitor, but it does not support Sentinel LPT

Tried Portmon (Sysinternals) – I can see port activity but not actual challenge/response data

Tried physical LPT passthrough in VMware Workstation (on a machine with native LPT) – program still requires the dongle to be present, and dump attempts also fail

My goal:

I would like to make a backup or create an emulator of my Sentinel SuperPro LPT dongle to secure my workflow in case of hardware failure.

I am not looking to bypass licensing, just to protect my own investment for business continuity.

My questions:

Has anyone successfully dumped or emulated a Sentinel SuperPro LPT dongle in 2024?

Are there any new tools, methods, or guides for dumping or logging challenge/response for this dongle type?

Is there any specialist or service you can recommend who might help with this type of backup/emulation for industrial software?

Any best practices for maintaining such legacy systems safely for the future?

Any advice, tips, or shared experiences are highly appreciated!

Thank you in advance for your support!

(If needed, I can upload photos of the dongle, failed dump files, or screenshots.)

Best regards, Dak

    Most likely your driver is the problem. What is the OS - DOS or Windows XP? The new dumpers are for XP most of them. You can try the old Safekey dumper. I have it somewhere but have to search for it.

    Hi,

     

    The hardware key is a Sentinel SuperPro from Rainbow SafeNet on LPT (25 pin) purchased in 2006, recommended Windows environment is XP professional service pack 1 (minimum), secured by Prinect Prepress Heidelberg interface.

    You can try with older drivers. This dumpers are made for older drivers. Recommend you to install 7.41 drivers. First remove 7.5 one. Or try with newer drivers also 7.6 or 7.8.
