INS-20802 Grid Infrastructure Configuration Failed - 11gR2 on Windows

Yesterday while installing Oracle RAC 11gR2 (11.2.0.3) on one of the client side got the below error.

INS-20802 Grid Infrastructure Configuration Failed

Although all the cluvfy verification passed successful already, above error occurred after the 84% of installation on the step of Grid Infrastructure Configuration. Before this error remote operations went smooth and all GI folders copied on the remote host successfuly. I did not cancel the installation and decided to investigate first to know the cause.
