Install Tool

Description of the installation script that is used to configure a TYPO3 system.

The Install Tool is a TYPO3 module that is used to install a new TYPO3 system or to modify the basic settings of a running system.

Basic Configuration

Information about access rights of the TYPO3 subdirectories, some TYPO3-related php.ini settings, a test for validating the server's e-mail settings as well as information on GD, Freetype, and ImageMagick or GraphicsMagick.

Among the changeable values are database settings (username, password, hostname, database name), the name of the TYPO3 site, the 'encryption key' (enhances overall TYPO3 security) and some other graphics-related values.

Database Analyser

Using this feature, all all tables and fields of the current database can be compared (that is, synchronized) with the neccessary tables and fields of the TYPO3 system and its installed extensions (option 'COMPARE'): Missing fields can be added, obsolete fields can be purged.

Another function exists to import the data of the extension static_info_tables.

There is also an option to create a backend user of the role Admin.

Update Wizard

[since TYPO3 version 4.x] This assistant tries to update a TYPO3 system to a newer version. Step-by-step various settings of the installed system are checked. Any changes are only applied once the administrator has approved them.

Before updating to a newer version, it is generally advisable to do a full backup of your TYPO3 system and TYPO3 database.

Image Processing

Here you can check the correct functionality of your ImageMagick or GraphicsMagick installation.

All Configuration

Most system settings can be changed in this section: graphics, system, extensions, backend, and frontend. A short text is displayed beside each setting that explains the effects of the respective setting.


During operation, TYPO3 creates a lot of temporary files in the directory /typo3temp and its sub-directories. With this option, those temporary files can be removed from the file system.

Clean up database

To enhance the rendering performance of a web site, TYPO3 stores many values (text blocks, image sizes, templates etc.) in the database (so called Caching). Using this option, those cached values can be deleted from the database.


This function displayed a slightly modified output of the well-known PHP function phpinfo(). It contains a lot of information on the installed PHP configuration, server settings and the like.

Edit files in typo3conf/

Here you can edit (writable) files from the /typo3conf configuration directory from within the TYPO3 backend. It provides a simple text area field to do the editing.


Behind this rather unremarkable heading you will find one of the most important settings: Here you can change the Install Tool password.

In case you forgot this password, we show you how you can easily reset the Install Tool password.
