Prathap,
The file you are looking for is called psi_iir.xml and it is usually located in your windchill loadpoint similar to this D:\ptc\installer\instreg\ii-7e3e4e23.128ea28da61.-8000. You want to use the one that contains all your install components. When you find that one, and if it is not name psi_iir.xml, rename it to this. There other similarly named files in this location, but some has numbers as part of the name like so psi_iir.001.xml and etc.
