I'm pleased to announce the second Release Candidate of the latest
For those not already familiar with RubyInstaller, these versions
continue the great work started with the original One-Click Installers
by providing both 1.8 and 1.9 versions of MRI Ruby for Windows.
RubyInstaller now uses a different compilation tool than the legacy
One-Click Installers. As a result, when combined with our optional
Development Kit, it is now possible to install RubyGems that, until
today, were not readily or easily available to Windows users.
This release also focuses on improving the installation process and
ensuring a much more pleasant experience for existing and new users of
Ruby on Windows.
= Before installing
If you're upgrading from previous RubyInstaller packages, please
uninstall these versions before proceeding. Don't worry, any gems
that you installed or compiled since installed will not be removed.
Since the new RubyInstaller uses a different compiler, we highly advise
that you avoid attempting to install over any previous One-Click Installer
installation, or any other variant versions (InstantRails, BitNami, etc.)
We recommend that you backup your previous installation, take note of the
details, your installed gem list, etc and proceed to completely uninstall
any legacy installations.
= Getting the installers and the packages
As usual, we distribute the installer and binary packages on our
project page at RubyForge. Please download from RubyForge the RubyInstaller
version that best suits your needs:
The following are the MD5 signatures of each component:
CHM Help Files:
Installers are meant for people with no previous or existing installations.
Installers are tested and signed by me, Luis Lavena, using a digital
certificate. The signed installers do not require administrative privileges,
and can be installed by users with limited system privileges.
Packages are meant for advanced users who want to configure the installation
to fit their needs. For example, installing multiple Ruby versions.
The CHM Help files provide access to both Core and Standard Library to
These files are already integrated in the installers, so the separate
downloads are for convenience purposes only
Packages and documentation has been compressed using 7-Zip compression
smaller file sizes and download times.
Out of the box, Windows do not support extraction of these files, but
can be easily downloaded
from from it's website: http://www.7-zip.org/
= What was improved or new in this version?
* Installers now properly manage switches when doing silent installations
(useful for automated deployment)
* Installers now correctly restore file associations on installation and
uninstall (issue found during rc1)
* Provided upgraded versions of all stable branches of Ruby: 1.8.6, 1.8.7 and
* No longer requires elevation of privileges with UAC enabled for
* Package newer 1.8.7 for future Ruby/Rails development as 1.8.6 for backwards
= Why so many versions?
Due the extensive server-base that currently runs Ruby 1.8.6, support
and releases for
this version will continue be provided. It is recommended that for
newer projects you
start using either 1.8.7 or 1.9.1, whichever suit your needs.
