After seeing this, I found that the user already installed RTC using Installation Manager 1.7.0 and so I uninstalled it, but while uninstalled it didnt ask for uninstall its related packages and also when I check the installed packages it dint show up the RTC package and no Installation Manager folder present in C drive Program Files.

After uninstalling I again tried the silent install, it again failed with same error, so I tried to install tjhe IM 1.7.3, at that time I am getting the below error 

ERROR: java.lang.IllegalStateException: No metadata found for installed package com.ibm.team.install.rtc.client.eclipse 4.0.6000.RTC-I20140205-1437-r406.

Installation Manager is not present in Registry (regedit) also.
