CREEPTD INSTALLER DOES NOT EVEN OPET TO INSTALL IT

Hello.

I have a huge problem with installing CREEP TD on my mac (latest version).
I go on creeptd official side and download it. When i start it, it opens creepTD icon in my docks and nothing happens.
And becouse it nothing happens, i click on the icon in the docks and it disappeared. and nothing happens.

It drives me crazy, becouse i have to use my windows7 !

Thanks a lot for your help!

Sounds like there's no Java 7 available on your computer. It won't start without.
