I am in the process of installing Ruby on Rails on windows 7. I installed ruby-1.9.2 (in c:\\ruby) and I\'ve installed rails using the gem install rails command
I'm a windows 7 user, and I was able to get rails working by following this guide: http://www.wiki.devchix.com/index.php?title=Windows_-_Rails_3 I know linking is frowned upon, but the windows 7 installations is quite detailed, and the devchix guide is excellent. I store my apps on the desktop in a folder called 'rails' not in the ruby bin.
