I'm trying to run 'Quickstart for Roadway Modeling using OpenRoads Technology Practice Workbook' When I click onto it to activate it I get the above (Screen shot) message in the window. I have got the latest version of Abobe Flash Player 20 ActiveX (Version 20.0.0.286) & it was installed on Jan 20th 2016. The latest version of Java 8 Update 66 (Version 8.0.660.17) was installed on 22nd Dec 2015. I believe that both Java & Adobe Flash are the latest versions so do not understand why I cannot access the Workbook. Can you please contact me to help me resolve this. Thanks - My email is Daniel.ahern@aecom.com
