If you have a French version of windows, ProBuilder will start in French when installed.

The french version of the language file is mostly incomprehensible and full of errors.

French speaking users will have a hard time understanding most of the menus.

To change it back to english

Open ProBuilder

Use the NAV thee to navigate to the system.property file located in the lib folder of your ProBuilder version

Right click on the file , select "Views" and use "Text File Editor" to open the file

Remove the '#' sign in front of the #niagara.lang=en

1) With the "#" sign removed

2) click save icon to save the modified file

Close the ProBuilder and restart it

Every menu will be back in english
