I had the same issue. I have added links to my vCenter servers' Web Client URL. When I launch them directly within Internet Explorer, the client integration plug-in is loaded fine. When I launch from within RDM, I get the notice at the bottom of the screen to "Download the Client Integration Plug-in".
I tried setting the IE mode to IE 10 and IE 11, but neither one makes a difference.
The plug-in is a 32bit plug-in, so I decided to try and edit the URL session to force 32-bit. This seems to have allowed the plugin to load, but the rendering of vSphere page is extremely slow now. Any additional thoughts or suggestions to improve this?
