The instructions for the configuration file are: Once downloaded, unzip this file into your user directory (c:\users).
This results in a folder epadd-settings nested inside epadd-settings (\epadd-settings\epadd-settings*). Based on a line in the the log file following my first failed attempt to process a folder, it seems presetqueries.txt needs to be at the top level, \epadd-settings\presetqueries.txt. I moved the contents of the lower folder up one level and everything seems to work now. So there may be an extra folder in the zip file?
