Mon logiciel fonctionnait puis il a bloqué.

J’ai mis fin à la tache avec le gestionnaire de tache. Impossible de d’ouvrir mon fichier : message " failed to launch jvm"

J’ai réinstallé ganttproject et java

voila l’aspect du logiciel quand je l’ouvre

la version est:

**GanttProject 3.3.3316 for Windows**

Quand je clic sur la croix pour fermer : la fenêtre devient immense

Aucun de mes fichiers ne s’ouvrent

Voilà la version de java que j’ai installée

Si quelqu’un peut m’aider

Merci
