Issue

Adobe Connect pre-9.0.3 users can experience the following:

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

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.

Solution

Starting with Adobe Connect 9.0.3, the Adobe Connect Add-in, on Windows, is compatible with Chrome browser version 25 running the default PPAPI Flash plug-in. If you are on Mac or on pre-9.0.3 Adobe Connect version, 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 (Figure 1).

    Expand details in the upper-right area of Chrome plugin screen
  3. Click Disable for the PPAPI (out-of-process) Flash plug-in Type (Figure 2).

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

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

    Note:

    Chrome updates usually take place automatically. After any Chrome update, PPAPI Flash plug-in is enabled and set as default. So it may be necessary to repeat the workaround.

Additional information

The default Flash Plug-in settings, since Google Chrome browser version 21 (on Windows) and version 23 (on Mac), prevent the Adobe Connect Add-In from launching. Chrome browser had earlier been shipping with only NPAPI Flash plug-in, which is compatible with the Add-in. However Chrome version 21 (on Windows) and Chrome 23 (on Mac) added a PPAPI (Pepper) Flash plug-in and made it the default. PPAPI Flash plug-in is not compatible with the Add-in. On Windows, Chrome stopped including the NPAPI Flash plug-in since version 22.

Although you can attend Adobe Connect Meetings without the Add-in, 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.
