How to use a ruby/python scipt in Emeditor?

I both installed ruby and python in my system (winxp, sp3)

Both of them work fine before.

And I just follow the Help of emeditor and try to run:

#language = “Python”
Window.document.write( ‘Hello’ );

or =======================

#language = “RubyScript”
Window.document.write( “Hello!” );

It popup a alert and said the Python/ruby is not registered.

Could anybody tell me how to resolve it?

Many thanks.
