In order to run the Zen Cart installer, you may need to do one of the following (after uploading a clean copy of zc_install from the distribution zip matching the installed version of Zen Cart):

  • Disable your alternative URLs plugin.
  • Add an rule to the .htaccess to not rewrite "zc_install".
  • Manually type in the full path (/zc_install/index.php).

  • Alternative URLs plugin not installed on this site this is from the htaccess file related to site in root directory (and others)
  • Add an rule to the .htaccess to not rewrite "zc_install". NOT NECESSARY
  • Manually type in the full path (/zc_install/index.php). Been doing this


Finally Plowed through the database upgrade issue by using the file hack described here:
https://www.zen-cart.com/showthread.php?216711-Can-t-upgrade-database-doing-upgrade-from-1-5-1-to-1-5-4

After I got the database upgraded I tried logging in to the admin area using two different user names. Got no love.

Heading off to attempt admin primary key corrections mentioned by mc12345678
