My apologies if the following is too elementary.

I don't know how other users run Ruby programs from Microsoft Windows, but =
I
mostly use batch files.
Or, to be precise, one batch file which takes various parameters to run
different Ruby programs using different versions of Ruby. (There are some
online utilities to help you do that, but I've temporarily forgotten what
they are called!)

A simple version is the following. Suppose you save your ruby program as
progname.rb in
  C:\ruby_programs_directory\
or whatever you want to call the directory. (It doesn't have to be a
directory in the root.)
You can set up a Microsoft Windows batch file with the following command
  call "C:\ruby19\bin\ruby.exe" -v "C:\ruby_programs_directory\%1.rb"
suppose we call that batch file rr.bat
Then you can run the ruby program progname.rb by going into
a Command Prompt window and typing.
rr %1

Does that help any?

(As X Heruacles said, if you post the script you have written, and also the
commands you are using to try to run it, then we may eb able to give you a
correction. From the error message, you are trying to run the script in
IRB?)
