Convert CCB to CCBI

I have a very old game created with CocosBuilder and need to update a CCB file, but do not know how to convert it to CCBI. I already downloaded the application from the GitHub repository (GitHub - cocos2d/CocosBuilder: CocosBuilder, the visual editor for cocos2d) but cannot find any .exe or .bat file to start it. I’m working with Windows. What do I need to do?

Cocos builder was a mac only tool. Im’ not sure if there was ever an .exe for it. You will have to build it yourself from code for Mac and use it.
