In general, you should need to type in the extension as part of the 
program name cos the extension is what tells Windows what to do with 
it.  The exception is a list of extensions that Windows treats as 
executables.  These are usually .exe, .com, . bat, .cmd etc - in these 
cases, typing the extension is optional.

This is controlled in a variable called PATHEXT in the environment.  In 
a command window, I did:
command>set

This gives me a list of extensions that are already there:
PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.RB;.RBW

(note .rb and .rbw at the end)

Add that to your PATHEXT and try?

Cheers,
Mohit.
