Do I need Internet Explorer to run ORD OpenRoadsDesigner?

Microstation requires me to have Internet Explorer installed. OpenRoadsDesigner is based on Microstation technology. This leads me to believe that ORD also needs IE to be installed, however I cannot find anything on this. Does anyone know wether or not I need Internet Eplorer? Also Internet Explorer will be replace by Edge in the future... how will this work out for (future) Bentley products?
