# OpenOffice.org/Installation
### Microsoft Windows

First you need to get an OpenOffice installer package. Before downloading the Office Package, you'll need to review the system requirement. After you read it, download an appropriate installation package or use P2P download or order a CD-ROM. You might want to use a download manager if you're using direct download.
For some functionality to work, OpenOffice need Java Runtime Environment (JRE) to be installed on the computer. If you're not sure you do have JRE installed, you could include JRE in your OpenOffice package.
Installation of both the JRE and OpenOffice.org is as simple as following a fairly standard installation routine in Windows. The installation wizard first explains that it will allow you to install OpenOffice.org. After you click on "Next", it prompts you to read and accept the terms of service. Clicking next again allows you to choose a directory in which to install the software. You are then offered a choice between full installation of all features and a screen which would allow you to choose which components to install. After this point, the installation wizard runs for a time, with several progress bars and a running list of which file is being copied.
You can now open OpenOffice.org from the task bar (if you set up quickstarter during install) or its program group. From the program group you then select the tool you need. To use quickstarter right-click on it and select the tool you need.

### GNU/Linux

Most GNU/Linux distributions come with OpenOffice.org preinstalled. It is simply necessary to choose the appropriate option for installation. Be aware, however, that some of the packaged files, such as RPMs, do not include some features that conflict with the distro licenses, as they are packaged by the distributors. Java support is one item frequently left out of these versions. However, some distributions configure it to run with an alternative free software Java Runtime Environment from the Free Software Foundation.
It can be installed in RPM or DEB form manually by navigating to the same download page as for installing under Windows, and selecting the operating system as Linux after choosing the language, then choosing whether you want to download an RPM (For Red Hat, Fedora Core, SUSE, Mandriva, etc.) or DEB (for Debian, Ubuntu, etc.) file. This can then be installed with the package manager provided with your distribution.
OpenOffice.org can also be downloaded in source code form by choosing 'Source and Solver' from the main download page, but this isn't necessary for most users not interested in development.

#### Debian and Derivatives

Debian and its derivatives (e.g. Ubuntu) use apt-get, aptitude, and synaptic as their package manager. You can install OpenOffice.Org by running either of these in the Terminal:
sudo apt-get install openoffice.org
or
sudo aptitude install openoffice.org
or by using the graphical package manager.

### Mac OS X

In order to run OpenOffice.org on MAC OS X, X11 is required. MAC OS X versions before Tiger (10.4.x) required a separate application to be downloaded from Apple. With Tiger X11 is available on the OS X Install Disk. You can find this in the System/Installation/packages/ folder called X11User.pkg - run this package to install X11.
There are community builds of Universal Binary OpenOffice.org for Intel based Macs; however the PPC versions will run in Rosetta anyway and are QA'd which the Intel builds are not at the time of writing. Once X11 is installed on the machine downloading and installing OpenOffice is like any other MAC application.
Go to the Openoffice.org web site and follow the instructions to download the application. Once this has finished, double click the "OOo_2.0.1_MacOSX_install_en-US.dmg" or ("OOo_2.0.3rc3_MacOSXIntel_en-US.dmg") package and then drag the OpenOffice.org Icon to your applications folder.
When the copying process has finished you can click the eject button in the finder and the dmg package can be deleted.
Click the OpenOffice.org icon to run the application, optionally register and you're ready to go.
