then when I see the wcf services in dynamics AX, system administration-> services -> inbounds , I noticed the service was red circled and it was not running state.
this was the reason of getting the error while installing components.
so I just did full compilation and then CIL compile, do server restart and then all services were OK and happily able to install the AX components EP etc.

hope this will help....
