Did that work for you? I had some trouble with it several years ago. If you don't specify a path to an exe inside a batch file, it will attempt to run the exe in the folder that the batch was run from. The issue I kept running into was the batch files I was trying to execute with WPI weren't located properly. (I'm sure that's user error on my part). What Kels is saying is the same thing I've been doing. Just to give a little more detail to his answer: Use winRAR to make an sfx (self-extracting) archive that contains the klite installer, the answer file (which you generate by following the instructions here: www.codecguide.com/silentinstall.htm) and the klite batch file. What I do is have the sfx extract everything to "C:\Temp", then automatically execute the batch file from that location.
