I think you mean this:

http://www.garbagecollect.jp/ruby/mswin32/en/download/release.html

But, be warned, is incomplete. See this ticket that has been stalled
for quite some time:

http://redmine.ruby-lang.org/issues/show/1459

The issue is actually simple: To be able to be fully 64bits, all
Ruby's dependencies must be compiled with 64bits.

That means several 3rd party libraries like zlib, readline, openssl,
curses, gdbm, tk, needs to be ported and compiled to use 64bits API.

While is doable, there is a lot of work required to do it.

Also, to achive that in the current state, requires you depend and
install Visual Studio on a 64bits platform, since using the express
you can't cross-compile, something not all developers have right now.

As maintainer of RubyInstaller project (known as One-Click), I'm
pretty aware of this and definitely is in our roadmap consider 64bits
versions.

This has been asked here (at ruby-talk) before and I've pointed to my
answer from January 2008:

http://rubyforge.org/pipermail/rubyinstaller-devel/2008-January/000230.html

Until all the minor details are ironed, you can still use the 32bits
version with no serious performance penalty.

I recommend you try our latest RC1 versions of the installer:

Hope this helps,
