Ok, thanks, I thought that was only a dev build and wasn't out yet.
I do need to have 32-bit installed also because I have a 32-bit java program that needs it.
And I have modified the environment variables for some other programs.
I'm am using the .exe when I open it the little loading bar pops up and disappears quickly then nothing happens, I have both 32-bit and 64-bit Java 6 installed.
