         The procedure described below is experimental, so if you believe you can improve this, please open an issue on Github for us with the proposed changes.<br><br>
 
         <h4>6.4.1. MariaDB</h4>

         Once installed, open the database client and create a user through the interface or issuing the following query (adapted to your needs):<br>
 <pre>mariadb> GRANT ALL PRIVILEGES ON chamilo.* TO chamilo@localhost IDENTIFIED BY 'some-password';</pre>
         Exit the SQL client.<br><br>
 
         <h4>6.4.2. IIS and URL Rewrite</h4>
 <a id="windows-install-iis-rewrite" class="anchor"></a>
-        If you are working on a Windows server, you should have IIS installed already. If not, you can download it from the official website (https://www.iis.net/downloads).<br>

         Once installed, you will need to restart IIS, close the network manager window if open, and possibly reboot the whole Windows machine for it to appear in the Site management (not the server management section).<br>
 
         <h4>6.4.3. IIS, CGI and PHP</h4>
 <a id="windows-install-iis-php" class="anchor"></a>
-        Once you have installed IIS and the URL Rewrite module, you will need to configure the CGI and PHP settings.<br>
-        CGI is an IIS module to enable (it's already present but needs activating) in the server manager. Open the server manager, click Manage &gt; Add roles and features &gt; pass screens until "Server roles". Select "CGI" under "Web Server (IIS) &gt; Web Server &gt; Application Development, then confirm the installation.<br>
-        Download PHP 8.3 for Windows from the official website (https://windows.php.net/download#php-8.3) (simple Zip version).<br>
-        This might require (depending on your setup) to install the VC++ libraries in version 14, which come from VStudio v16 (between others). If you don't have them yet on the Windows Server, you can download them from here depending on your architecture: <a href="https://aka.ms/vs/16/release/VC_redist.x64.exe">x64</a> or <a href="https://aka.ms/vs/16/release/VC_redist.x86.exe">x86</a>.<br>
-        Add PHP to the PATH environment variable (e.g. C:\php): Settings &gt; System &gt; About &gt; Advanced system settings &gt; Environment variables, then select "Path", click "Modify", click "New" and introduce "C:\PHP", then validate twice.<br>
-        In the IIS manager window, when the server is selected and you click on the Mappings manager, click on the "Add module mapping..." in the right panel and make sure request path "*.php" is mapped to the FastCgiModule. If not, add it.<br>

-        Change permissions so the web server user is able to write to var/, config/ and .env during the installation. These permissions can be removed later on, to the exception of var/ which has to remain writable by the webserver. These permissions need to be set in a way that the owner of the IIS service (possibly "System" or "IIS_IUSRS") can read and write to those files and folders, otherwise the installation script (which needs to write some files) will not be able to proceed.<br>
