There is only one "version" of Tube Toolbox software to download and install on your computer. You can download it from our website at http://www.tubetoolbox.com/Download.aspx. When you log in, the software will check to see if the channel you log in with has a Tube Toolbox Professional subscription or not. If it does, then all Tube Toolbox features are available to you. If you do not have a Professional subscription, you have a Personal subscription and only have limited access to Tube Toolbox's features.
