To launch a meeting in the browser window, install and enable the Flash Player in your browser. If Flash Player is not installed or is disabled, Adobe Connect meeting room does not open in a browser. Instead, it prompts to install the Adobe Connect application.
If the Adobe Connect meeting still does not open in the browser, append ?launcher=false at the end of the meeting URL. For example, if your meeting URL is "meetingroom.example.com", then open "meetingroom.example.com/?launcher=false".
If the issue continues to persist, contact the Adobe Connect Support team here.
