The BrightTALK Pro Webinar tool does not require Adobe Flash for audience to viewing. Outdated browsers of IE10 or earlier are the exception as these browsers still require flash to view videos. Make sure your audience is using IE11+, Chrome, Safari or Firefox.
Your audience must have Adobe Flash 10.2.13 or later in order to view live BrightTALK Standard webinars on a desktop browser.
iOS and Android devices now support the viewing of live and recorded BrightTALK Pro webinars, as well as recorded standard (slides & audio) webinars.
