Error opening scene builder

Question

I\'m making a program with Javafx Eclipse and I get an error when I open the program with the Scene Builder

This is the error:

Answer 1

Those of you who are using MacOS ( in my case ), Go to JavaFx from preferences then browse to application folder and select scene builder.

Doing other ways wont open the exact file you are trying to edit (It may make a new file which will be untitled and you have to save it manually on the project directory). Also right clicking the fxml file, you wont be able to use the option (open with scenebuilder).
