I don't understand what you mean by 'use them directly'. From your 'Framework 2.0' folder, I copied the CuteEditor.dll, NetSpell.SpellChecker.dll and CuteEditor.lic into the bin folder of our site (overwriting the existing files). Also, copied the entire 'CuteSoft_Client' folder from your 'Framework 2.0' folder into the site (overwriting the existing folder).
Is there another step? Thanks.
