Just as an FYI, when even you install a new Oracle product on top of the existing Oracle Products, Oracle makes the default Oracle Home to the Home of the newly Installed Products. To recognize the previous TNS Names.ora which you have build painstakingly, all you have to do is change the dafault home by using Oracle Home Selector by going to Start-->Programs-->Oracle Installation Products-->Oracle Home Selector

Change it back the previously installed Oracle Home, and you would successfully connect to all your TNS Services without "ORA-12154: TNS:could not resolve service name" error.
