Starting with Creative Cloud 2015, the Extension Manager is no longer available to install add-ons and extensions for Adobe applications. Add-ons are now installed through the Creative Cloud desktop app. To install third-party extensions, you can use the Extension Manager (ExMan) command-line tool. 

Install add-ons

  1. Download and install the Creative Cloud desktop app.

  2. Open the Creative Cloud desktop app, click the three vertical dots icon in the upper-right, and then select Preferences.

    • Ensure that the version of the application is greater than
    • Click Creative Cloud and select Files. Ensure that File Sync is enabled.
  3. Install Adobe applications featuring the add-ons, if they have not been previously installed. For example, if you are installing the Server Behaviors and Database extension for Dreamweaver, ensure that Dreamweaver is installed, too.

  4. As the add-ons are installed automatically, you receive notifications. If you do not see the notifications, go to My Add-ons to install your add-on. If the add-on has been installed but you don't see it in the application, uninstall and then reinstall the add-on:

    • Go to My Add-ons, find the add-on name, and click Remove
    • Reinstall the add-on as in steps 1 and 2 above. 
  5. To verify whether the add-on has been installed, open the web page for the add-on and see the section Where to find it.

    If you have issues installing add-ons, download the ZXP file using the link Download Using Extension Manager under Where to find it. Then, follow the steps in Install third-party extensions.
