Flash and "Network Visualization" tab in vSphere Client

I am trying to set up vCloud Director as per the evaluation guide (https://my.vmware.com/files/pdf/products/vCloud/VMware-vCloud-Director-51-Evaluation-Guide.pdf), page 40 under "VXLAN Preparation", and when I click the "Network Visualization" tab, it says "To view this page ensure that Adobe Flash Player 10.0.0 or greater is installed."  I have version 11 installed.

Is there something I need to do?  Find the 10.0 version and install that instead?

Thanks,

Tom
