How do I perform a silent install with the RubyInstaller?
The RubyInstaller currently uses Inno Setup which allows two levels of silent installation (silent with just an install progress window, or very silent without even an install progress window) to be selected using either the /silent or /verysilent command line options. When performing silent installations, you often want to specify where to install the Ruby environment and whether the RubyInstaller should associate .RB/.RBW files and update your PATH environment variable to use the newly installed Ruby.
