Summary

Starting from FNP 11.19.0, (shared Wibu dongle driver version 6.60 and DLL's version 6.60) the dongle DLL will not be backwards compatible with FNP 11.18.3 and older versions of clients.

Symptoms

Starting from FNP 11.19.0 and the Wibu Dongle Drivers are not compatible and getting the error "WIBU DLL Signature not matched", when trying to fetch Wibu-id from the older FNP client kit with the latest driver 6.60 and WkWin32.dll or WkWin64.dll version 6.60 installed.

As per the FlexNet Publisher 2023 R1 11.19.0 Release Notes (March 2022) this is a known dongle issue due to the change in the DLL signature from "Symantec" to "DigiCert". 

Steps to Reproduce

1. Download and extract the latest FNP toolkit 11.19.0 or the latest and build the toolkit for DONGLE. nmake -f makefile.act DONGLE=1
2. Install the latest Wibu dongle device driver 6.60 and make sure the WkWin32.dll or WkWin64.dll are placed correctly into C:\Windows\SysWOW64 or C:\Windows\System32
3.  Plugin dongle 10 into the device and run lmhostid -flexid -long to fetch from dongle 10 device.
4. Now, Try fetching flexid using the FNP 11.18.3 or older version kit and observer the error "WIBU DLL Signature not matched"

Workaround

In case of backward compatibility support, try to use old DLLs (version less than 6.60) with the latest drivers 6.60 to support older clients.
