Ruby Interpreter not running scripts

Hi

Have you had this happen to you? I have installed ruby and added all
gems. However, when I try to run any script just be double clicking the
file, the file opens with scite and doesnt run. I tried to change it to
open with the Ruby interpreter (CUI)1 but it still doesn’t run. My paths
are set to c:\ruby\bin and my pathext is set to .rb;.rbw. Is there
something that I am missing?

Thanks MC
