OpenOffice.org 3 requires one of the following operating systems:
- Microsoft Windows 98, Windows ME, Windows 2000 (Service Pack 2 or higher), Windows XP, Windows 2003, or Windows Vista
- GNU/Linux Kernel version 2.2.13 and glibc 2.2.0 or newer
- Mac OS X 10.4.x, X11 required; Mac OS X 10.5+ without X11
- Solaris version 8 or higher
Some OpenOffice.org features (wizards and the HSQLDB database engine) require that the Java Runtime Environment (JRE) be installed on your computer. Although OOo will work fine without Java support, some features will not be available. You can download OOo with or without JRE included.
