The QTI converter won't work unless you have the Python QTI 1.2 to QTI 2.1 converter installed The plugin will first check to see if the python app is in "RAILS_ROOT/vendor/QTIMigrationTool" We generally have the QTIMigrationTool checked out somewhere on the system and symlink that to the expected directory If the QTIMigrationTool isn't in that location the plugin will just try to run the executable and see if it works. So if you have the QTIMigrationTool in your system path it will work as well.
