Issue

The default Flash Plug-in settings, since Google Chrome browser version 21 (Windows) and version 23 (Mac OS), prevent the Adobe Connect Add-In from launching. Chrome browser previously shipped with only the NPAPI Flash plug-in, which is compatible with the Add-in. However, Chrome version 21 (Windows) and Chrome 23 (Mac OS) has a new PPAPI (Pepper) Flash plug-in, which is the default. The PPAPI Flash plug-in is not compatible with the Add-in. On Windows, Chrome stopped including the NPAPI Flash plug-in since version 22.

You can attend Adobe Connect Meetings without the Add-in. However, the Add-in is required for functionality like screen sharing and making offline recordings. While Adobe works on a solution, use the workaround below or use a different supported browser for your Adobe Connect Meetings if Add-in–specific functionality is required.

Symptoms

Adobe Connect 8 and 9 users can experience the following:

  • Even if Add-in is installed, the meeting opens in the browser and not in the Add-in.
  • When attempting to share the screen, the following message appears:

On-premise customers, using older versions of Connect 8, can experience the following:

  • Any Add-in-specific functionality (like screen sharing) starts the Lightning download for Add-in. However, the download still fails.
  • Installation of the Add-in from the Help menu in the meeting fails.

Solutions

Until PPAPI Flash plug-in becomes compatible with the Adobe Connect Add-in, use one of the following workarounds:

  • Use supported versions of browsers, other than Chrome, if Add-in specific functionality is required in the meeting
  • Disable the PPAPI Flash plug-in and enable the NPAPI Flash plug-in in Chrome as follows:
  1. Type chrome://plugins in the browser tab.

  2. Expand Details, in the upper-right area of the screen, if needed.

  3. Click Disable for the PPAPI (out-of-process) Flash plug-in Type.

  4. Check if there is at least one NPAPI Flash plug-in listed below the PPAPI Flash plug-in. If it is, make sure that at least one NPAPI Flash plug-in is enabled. Then refresh the Connect meeting client tab in the browser.

  5. If no NPAPI Flash plug-in is listed, then install it from get.adobe.com/flashplayer using Firefox or Opera browser. After installing it, refresh the Connect meeting client tab in the Chrome browser.

    Note:

    Chrome updates usually take place automatically. Before Chrome version 23, any Chrome update applied re-enables the PPAPI Flash Plug-in. So it's possible that you have to repeat the workaround.
