Adobe Connect 10.5 and HTML5 update

With the HTML client, participants can seamlessly join a meeting, a virtual classroom, or a webinar in their web browser without downloading additional software. Inside the HTML client, users can view shared screens and content, interact with notes, leverage VoIP in the form of transmitting and receiving audio, and view a shared live video. Users can also participate in polls, chat, and Q&A.


Apart from the HTML client, participants can continue to join through the previously supported methods—the Adobe Connect desktop application and the Adobe Connect Flash-based browser client.

The HTML client supports the most commonly used features for attending and participating in meetings, virtual classrooms, or webinars. However, the HTML client in its current form does not contain every capability that the other Adobe Connect meeting clients possess. For more information on what is supported, see Adobe Connect Capabilities in HTML Client.

Account administrators and room owners can choose whether to enable or disable the HTML client for participants at the account or room level. For more information on how to enable these settings, see Enabling Adobe Connect HTML Client.
