How can I upgrade an older version of OpenOffice.org to a newer one?

It is recommended that the previous version be uninstalled before updating to a new version. This can be accomplished, in Windows, by using the Setup program from the Start Menu and selecting Deinstallation.

You can also copy and rename the main OpenOffice.org program folder if you want to keep some or all files contained in it. If you try to install a new version over an older one on a Windows system, you could have an error during the installation procedure.
