Hi, has anyone successfully running the Cisco UCS plugin with vcenter server appliance 6?

I’ve used the Cisco plugin registration tool and tried plugin version 1.2.2 and 1.2.5. Still can’t get it to show in web client. The tool says it  was successful , the event logs show successful registration of the plugin, yet i don’t see the plugin at all. I’ve restarted the server multiple times so that cant be it. I’m thinking it doesn’t work with vcenter server appliance?
