At first I only knows the situation under Linux and have written the changes of the files in changedFiles.zip.
It creates some bash-scripts for Windows and Unix (depending on which system you running it), to start the Runtime and the GUIService.
Then I tested it on Linux and on Windows. And wondered, that on Windows the GUIService already starts, after myrobotlab.jar was startet.
I think the Runtime-script have still its right to exist. But the Windows version of the generated script possibly not. If you want, then try my changes out.
