According to the SuiteCRM install guide, after you've copied all the neccessary files to your webroot directory you are supposed to hit domain/directory/install.php
Unfortunately I am missing the desired install.php file.
I downloaded the fresh 8.4.0.zipand also one version below.
Do I miss something crucial?
Please refer to the image below, where you can see the contents of my directory:

You are following SuiteCRM
7.*documentation for installation while you have downloaded SuiteCRM8.*.In SuiteCRM 8.*, the
install.phpfile is located at the following path:For SuiteCRM 8.* installation, please use the following documentation: https://docs.suitecrm.com/8.x/admin/installation-guide/downloading-installing/
(I am not pasting the exact steps as the documentation gets updated frequently and the steps might change)
