Webcast Troubleshooting Tips
Here is a list of our supported browsers/versions:
*H.264 video (required for viewing Vimeo videos) is only supported in Firefox for Windows 7 and later. Firefox versions on Windows XP are no longer supported for playback.
*Older versions of Internet Explorer (IE 10, 9, 8, etc) that lack support for the TLS 1.2 protocol and HTML5 cannot be used to play Vimeo videos. As of January 12, 2016, Microsoft has stopped releasing updates to older versions of IE.
