I was able to integrate the loadrunner with selenium .but when i click on controller submenu from devops option ,i could see below exception.

Error while launching the Controller: Exception "The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))" was handled.

Can someone help me on this ?
