Im not an expert on the products, but I do not believe, that those are diffent version. I think they talk about integration to other products. If you do not have the DotNetNuke whatever version or IbuySpy or Community Starter Kit, do not think to much about what chat you want, just download the Cute Chat and Web Messenger standalone  version 2.0.

 

I'm not working for CuteSoft and Im not associated with CuteSoft in anyway, just trying to help you with a quick answer before the weekend ;-)
