Eclipse won't open after Installing Windows Builder

Question

I downloaded Eclipse's Windows Builder through this link which is from Eclipse org itself. After the installation was complete, my Eclipse just won't open anymore. There's no errors log, it will appear the loading screen and close. as you can see on this video.

How can I fix this problem? Thanks

EDIT: The last session was 2015-07-04 at 11:45. This was when I tried to download and install Windows Builder. It is filled with a bunch of "(something) will be ignored because a newer version is already installed" and at the very bottom this is the last thing that it shows

Sorry if it's disorganized

You will probably need to try to repeat the process with a clean installation of Eclipse.

One thing you can try changing is where it downloads the WindowBuilder plugin from (got that idea from here). Go to the WindowBuilder website and copy the "Release Version" "Update Site" link for your version of Eclipse. Paste that as the "source" in the "Install New Software" window.

The link for Eclipse Luna should be:

http://download.eclipse.org/windowbuilder/WB/release/R201506241200-1/4.4/
