When trying to start the Web Listener-Configuration utility, the following error is encountered:

WLCplExe.exe - System Error

The program can't start because the Ltkrnu.dll is missing from your computer. Try reinstalling the program to fix this problem.


The core LPS Client Install files do not have the correct set of DLL files to run the Web Listener-Configuration utility.


This has been corrected in Loftware Print Server 12.0.1. Click on the following link to access the Loftware downloads section (requires a userid and password from Loftware Customer Account Management)
