Hi Kutti
On the sourceforge location of fudaa-prepro you could find the latest version 1.1.0
You could only download the jar file (not install.bat nor prepro.jnlp) but this is sufficient for running it.
Try to click twice on the jar file and normally this could run without any problem.
If not you could generate a small file prepro.bat which contain the following line:
java -jar fudaa-prepro-1.1.0.jar
Hope this helps
