Ich weiß nicht ob das jetzt hier reinpasst aber ich versuchs mal:
Also ich hab alle Softwarekomponenten für den RP6 installiert und wollte nun den RP6Loader starten. Dabei kommt dann immer eine Fehlermeldung, bei der irgendetwas mit Java nicht stimmt.
Ich betrete mit dem RP6 in Sachen Roboter Neuland, also wäre ich für jede Hilfe dankbar Bild  
Ich geb mal meine Log-file mit dabei, vielleicht kann dann jemand von euch mein Fehler erkennen
Schonmal vielen Dank!!
