FCKEditor installation questions

I'm having a difficult time understanding how exactly to get FCKEditor installed into WYSIWYG. My primary confusion is, do I need both the FCKeditor module AND the download from fckeditor site? I copied the fck download contents into libraries as WYSIWYG suggested, but get the error "The version of FCKeditor could not be detected." One issue I see is that the js file is called ckeditor.js, not fckeditor.js as noted on the WYSIWYG page.

So do I need to install the module as well? (In which it's directions instruct you to download the FCK download into the modules own subdirectory.

Any help straightening this out would be greatly appreciated!
