Dappler 6.0 is the Audio Player component of CampaignManager 6.0 and needs to be installed onto a Player PC. To operate the Dappler Player, you need to download CampaignManager 6.0 and select to install Dappler player during your installation process, the same as you would for CM Player. In the case of Dappler though, the files in the Campaign are in audio format. Dappler can run in the background of CMPlayer, or on its own PC.
