Rubyinstaller for Windows - ruby does nothing

I've tried using Ruby 2.0 x64 and Ruby 1.9.3 for Windows using RubyInstaller. Entering ruby -v works as expected, and running gem gives me the expected usage docs. Running and using the Interactive Ruby application works as expected. I am running Windows 8.1 Update.

However, for both installations, running ruby from cmd gives me a blank prompt where I can type, but nothing is executed when I press enter. If I attempt to install a gem, there is a similar issue where the program is running, but there is absolutely no output, and nothing happens.

I can't seem to be able to find a similar issue elsewhere. Does anyone know what might be wrong, and how I could fix it?

What did you expect to happen? ruby.exe is the ruby interpreter, meant for running ruby scripts. Normally, to use it you would create a file containing valid ruby commands with your favorite text editor (but not a word processor). If you save the file as foobar.rb, typing ruby foobar.rb (or if you told the installer to associate .rb files with ruby, typing just foobar.rb) will execute the commands in the file as a script/program. If you don't supply a script file name, ruby goes into input mode and expects you to type in a program on the spot. It won't give any feedback until you indicate end-of-file by typing CTRL-z, at which point it will process what you typed and most likely tell you about all the errors you made. If you want line-by-line interactive feedback, use irb.
