Crash report au lancement

Bonjour, en ce moment je souhaite installer minecraft sur mon pc. J'ai essayé plusieurs launcher (shigninima, lifecraft, team extreme) mais aucun ne marche à cause des crash qui arrive au lancement du jeu. J'ai été voir sur plusieurs forum mais aucun ne me donne la bonne solution. S'il-vous-plaît aidez moi.
Crash report lifecraft:
