Cakewalk by BandLab is not (or at least was not) run from the BandLab site. From BandLab one downloads the installer and runs it. Then you let the installer download and install Cakewalk by BandLab and whatever extras they now have (eg the Melodyne demo). Once installed the download tool just sits there, a download tool will be required for updates etc.

If you have a present install of Sonar, Cakewalk by BandLab will pick up all the goodies you may have loaded. It will also pick it any VSTs (assuming you have the correct paths set in preferences). As said many times Cakewalk by BandLab is basically Sonar Platinum without all the add ons. In reality it is the add ons that really cost.

My two bobs worth
