After successful v1.6 installation, I am advised to remove 'install' directory. But, I can't it. Is it the 'setup' folder?
Also, i think it's a typo. It should have said, change permission to 444, not 644, to remove write access. Is that correct?
Thanks.

Finishing Up
If the setup script has finished running with no errors, then congratulations osTicket is installed. Your next step should be to fully configure your new support ticket system for use, but before you get to it please take a second to cleanup.
* Change permission of ostconfig.php to 644
* Delete install directory.
