Either using Windows Explorer or Mozilla/Netscape's Download Manager, navigate to the Apache OpenOffice file you downloaded.
Windows Explorer users will want to find the file and double-click to launch the unpacking and installation program. Alternately, Mozilla/Netscape users will want to open the Download Manager, highlight the file, and click Launch File. In either case, the unpacking program will start.
The Welcome window is displayed to note that you have downloaded Apache OpenOffice 4.x.x. Click Next to continue.
The Select Folder window is displayed. Accept the folder name displayed in the text box or enter the name of the folder in which to save the unpacked files, and click Unpack.
Once the files are unpacked, the Apache OpenOffice 4.x.x Installation Wizard is displayed. (See Windows Overview for what to do in an upgrade situation.) Click Next to continue installing Apache OpenOffice 4.x.x. Follow the prompts, and Apache OpenOffice will be installed on your system, ready for use.
