Hello Ian, Try the below steps : Let me know how it goes. Thanks, Vikram KV  
New vCenter 5.5 (build 2646482) latest from VMware website. vSphere client 5.5 (of course) Shiny new V3.0 of OMIVV Install appliance and registered in vCenter without error. Seems to work in the VMware web client (I'm still exploring). I can add servers iDRACs manually. From the Win32 fat client, I don't get the wizard but I do get an empty bar in the middle of the screen with "Error #2048" down the bottom. My client is Win7 x64 with IE10 as the default browser. Where do I begin ??? Cheers Ian      
Version 3.0 on vCenter 5.5 using vSphere client
