You explained to me before but i think i found the problem.
You got windows 7, 64 bit
Did you download JDK7 and JRE7?
If you go to the java website, download the JDK 1.7.0 for windows 7, 64bit
after that,
- go to your computer
- open C:
- open the folder program files (x86)
- open the folder Java
- check if there is jre7 and jdk7
if you do both both, nothing can go wrong.
