Hi there,
I have the same problem here.
Did you found a solution for this?
In my lab I had used 2 vCenter (Version 5.1.0 Build 1064983) and 2 nodes (ESXi 5.1.0 Build 799733) for each vCentre
My vSphere client is 5.1.0 Build 78611
Everything works fine under Web Client but under vSphere I could not install the VRM plug-in with the message:
"no client side download is needed for this plugin".
Any help is appreciated.
Regards
Antonio
