or just force install cocos2d-x 2.0.3 ?

somebody teach me right step.

You need to delete manually the old version folder and install the new version.
Sorry, but I don’t remember exactly where cocos2d-x folder can be located.

The files in Classes are your source code.
Thats files copy and paste on cocos2d-x-2.0.3 project’s Classes folder.
