This message:

"ruby is not recognized as an internal or external command operable
program or batch file."

Means ruby is not in your PATH.

If you installed Ruby as administrator, it should have modified your
PATH. For the change take effect you will need to logout and login
again to be able to use the command prompt.

Also, ensure that PATH contains the bin folder where ruby was
installed (by default C:\Ruby\bin)

So:

C:\>set PATH

Should display the current path. Look for Ruby\bin in it.

If not, you will need to add manually from the system properties:

Start -> Settings -> Control Panel. Double click on System. Go to
Advanced tab, and then Environment variables option.

From there append the Ruby path to the end of the PATH system
variable.

After it, hit Ok and logout.
