Pentaho BI platform x64

Hi guys,

I am new to Pentaho so I am sorry if my questions are bad/dumb.

I downloaded Pentaho BI server from http://sourceforge.net/projects/pent...?source=navbar

But there is only a x86 version.

I am trying to install it on a MS Server 2008R2 x64 and I need a x86 version of the installer.

Does anyone knows where to find it?

Thanks in advance
