vSphere Client error : An internal error occurred in vSphere Client Details An item with the same key has already been added

August 23, 2012 1 comment

This morning when I opened my vSphere client I had this pop-up error message displaying:

I did some research and found this VMware KB: 2030029 but the solution says to disable the VMware Update Manager Plug-in. Solution???

So to fix my issue and keep the plug-in I had to remove my windows profile from the machine running the vSphere client and re-create it.

Scenario: vCenter 5.0, vSphere client 5 and Windows Server 2008 R2.
