Re: Data Base Patch
if you've renamed your installation folder as you should have, rename it back to zc_install and then open your_site_url/zc_install/index.php in your browser. You'll be able to do just a database upgrade from there. Once done, don't forget to rename or remove that installation folder again.
Alternatively, you can go to Admin > Tools > Install SQL Patches, upload a copy of mysql_upgrade_zencart_1301_to_1302.sql from the zc_install folder on your hard drive by using the browse button and running it.

An assumption is what you arrive at when you get tired of thinking...
