I'm using Gluon Scene Builder but it fails when i want to run any fxml files on Netbeans 8.2. It says like "Failed to launch JVM". I tried all stackoverflow replies but it didnt help my problem. Please help!!!
I solved it at last. The problem is the system user's name. It has some blank like "Java Engineer". I uninstalled scene builder from "Program Files" folder and renamed default system user as "JavaEngineer" then installed again to default path into "AppData/Local/Scenebuilder" folder. At last i fixed right path to Netbeans as "C:\Users\JavaEngineer\AppData\Local\SceneBuilder". It works fine!!! So i can advice for this problem, users have to change their default user name. Thanks!!!
