When we shipped Adobe Bridge CC, it did not include the Adobe Output Module (AOM), which allowed you to create PDF Presentations and Web Galleries. The team has worked some magic and the Adobe Output Module is now available for Bridge CC. Use the instructions in the following document to install it: How to install Adobe Output Module in Bridge CC.
In addition, make sure you have the most recent version of Bridge CC installed. To check for updates, in Bridge, choose Help > Updates, and then follow the instructions to install any updates.
