That's javacpl.cpl in the bin-subfolder of your java jre folder. What happens if you doubleclick that?
There's also a javacpl.exe. Gives the same result with me. What happens with you?

I have windows 8, and I have read from Java's site, how to open control panel. But it wont open, a box appears in the upper left corner of my computer screen and then nothing. Nothing at all.
I tried that I shut my computer and try again. It won't just open
