The Ruby Installer 1.8.1-13 (final) for Windows has been released and is now available for download. This release fixes most of the problems with RI. One remaining RI problem is that it still fails with all uppercase items (like "RI CGI" and "RI IO"). Win32ole is working much better than in the previous release, but it still has problems. All other reported problems have been fixed (I hope :-).
