Not able to run Eclipse Galileo

I am trying to run Eclipse Galileo, but having following error message on screen:

I have installed jdk-6u21-windows-x64 and also added the environment variables in the PATH. I am runn开发者_运维问答ing Windows 7 64-bit.

If you're going to use a 64-bit JDK, you should probably get the 64-bit Eclipse instead. They really should match.
