What do you mean you cannot find that file?
application/config/routes.php
If it is not there then you have a problem! Because I can run CI 2.0.2 with no problems!
Maybe when you downloaded it was corrupted. I have had problems in the pass were I had to download it 3 or 4 times to get a clean copy that would work.
