Just download RC2 version of RubyInstaller for 1.9:

http://rubyinstaller.org/

It will install by default into "Ruby19" at the root of your system
drive (generally C:)

By default, it will not change the settings of your environment, and
you can start it from the customized command prompt shortcut that is
created inside All Programs menu.
