## Microsoft Windows

- Windows XP, Windows 2003, Windows Vista, Windows 7, Windows 8 ***)**
- 256 Mbytes RAM (512 MB RAM recommended)
- At least 650 Mbytes available disk space for a default install (including a JRE) via download. After installation and deletion of temporary installation files, Apache OpenOffice will use approximately 440 Mbytes disk space.
- 1024 x 768 or higher resolution with at least 256 colours

 ***)** AOO 4.0 has been tested succesfully with Windows 8.  AOO 4.0 is not yet [Windows 8  certified][5].

## GNU/Linux ("Linux")

- Linux kernel version 2.6 or higher, glibc2 version 2.5 or higher
- 256 Mbytes RAM (512 MB recommended)

## Java

- The Java Runtime Environment (JRE) 1.5.x, is the minimum version required to use full Apache OpenOffice functions that need Java.
(see [Java and Apache OpenOffice][4].) However, we strongly recommend the last version of Oracle Java 1.6.x, patch level 45,
or the latest Oracle Java 7, or, for Linux users, OpenJDK 6, build 27, or OpenJDK 7. 

## For accessibility

### All platforms

- Java runtime environment 1.4.0_02 / 1.4.1_01 or newer
- Java Access Bridge (to get the [Java Access Bridge][2])

### Linux:

- Installation of GNOME 2.10 or higher
