TYPO3 Core

I tested it again and found out the following:

• Regular installation without downloading the list of distributions --> RTE is activated
• Same as above + downloading the list of distributions --> RTE is not activated - see the short install video I made :)

I guess it has something to do with the user config setting in file: /typo3/sysext/install/Classes/Controller/Action/Step/DefaultConfiguration.php (line 36-45)

        // let the admin user redirect to the distributions page on first login
        if (isset($this->postValues['values']['loaddistributions'])) {

            // update the admin backend user to show the distribution management on login
            $adminUserFirstLogin = array('startModuleOnFirstLogin' => 'tools_ExtensionmanagerExtensionmanager->tx_extensionmanager_tools_extensionmanagerextensionmanager%5Baction%5D=distributions&tx_extensionmanager_tools_extensionmanagerextensionmanager%5Bcontroller%5D=List');
            $this->getDatabaseConnection()->exec_UPDATEquery(
                    'be_users',
                    'admin=1',
                    array('uc' => serialize($adminUserFirstLogin))
            );
        }
