Hello.

Try to change your user variables environnement with a JDK 1.7 last rev (don't work with the latest 1.8) that you have to download... It should work.

My Windows is a 64b system... If your is a 32b you have to put Program Files (x86).
You'll have to rebuild all your server after you have made your config.

Your problem should be solved.
