Bitrix. How to reset user with id=1?

Question

1C-Bitrix

Hello.
Such situation. You need to restore the site on Bitrix. There is a database, there is access to ftp. But the problem is that the Bitrix license has expired and standard methods like

<?
require($_SERVER["DOCUMENT_ROOT"] . "/bitrix/header.php");
global $USER;
$USER->Authorize(1);
LocalRedirect("/bitrix/admin/");

no longer help - except for the page with the message "The trial version of the product has expired. You can buy a fully functional version of the product on the site" does not go anywhere. There is a working key. They said that you need to reset the user with ID=1. What to do, tell me

Answer 1

Try to paste the key into the /bitrix/license_key.php file and delete cache folders
