the problem is that when i try to open it nothing happens.
i reinstalled java7, and the same happens.
when i first downloaded it, it asked me what program to use to open it. i had to go to my java folder and tell it to use java.
I then verified and uninstalled java 6 components and tried again. this is the error i got.

i then told it to use java web launch and got this error.
"Bad Installation. no JRE found in configuration file.
