In short you need Odin v 3.xx Need to have the Drivers installed for your phone. Make sure Kies is not installed on your PC. Put your phone in Download mode and then connect to pc. Flash the Root66 file and you are done. There are several tutorials on Youtube for how to use Odin.
Note - For your Knowledge, please read on the 4.3 and its locked bootloader.
