Why does my Ruby 'ri' tool not return results in command prompt?

Greetings,

When I try to use Ruby's ri tool in a command prompt window to acquire information about classes, methods, etc. it seems to always fail. For example if I type 

ri Array

I get a message saying 

Updating class cache with 0 classes... Nothing known about Array

What should I do to configure Ruby's ri tool to work?

Thanks.

NOTE: I am using Vista 64 with Ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32] installed. (thanks MikeJ)
