Why can't I installed my createJS extension?

helo guys and all Adobe administrator, I'd like to ask you a few question, such as :

- How can't I installed the createJS extension for Adobe Flash CS 6?

- Are there any specifications or newer version to install it?

Well for your info, I'm using Adobe Flash Professional CS 6 6.0.335.0 now.

Thank you for advise.
