It seems like the traditional ways are always the best. Having no idea _why_ the web server was truncating the download file, the server got rebooted, and everything now seems fine. So, feel free to start downloading the Ruby 1.6.2 installer from http://www.pragmaticprogrammer.com/ruby/downloads/ruby-install.html We took the opportunity to fix the broken link to RubyWin from the Start menu. However, there is still an outstanding issue with using putc inside RubyWin: we're working on this. Enjoy, Dave
