OpenOffice

OpenOffice is an open-source word processor software developed by Apache Software Foundation, which includes several features present in Microsoft Office and other word processor software like LibreOffice.

OpenOffice requires at least Windows XP, OS X 10.7 (Lion) or Linux with kernel version 2.6 or higher and glibc 2.6 or higher, as well as 256 MB (Linux/Windows)/512 MB (OS X) of RAM, a screen resolution of at least 1024x768 and 256 colors (8-Bit) and 400 MB (OS X/Linux)/650 MB (Windows) disk space. Recommended are 512 MB of RAM and 16,7 million colors (32-Bit) as well as a installation of the Java Runtime Environment 1.5 Update 45 or newer.

OpenOffice is known for the lack of a 64-bit version for Windows. On these systems, it must rely on the WOW64 emulation system. Also there is no version for M1 processors, so it must rely on the Rosetta emulation system on macOS.

Former developers are Sun Microsystems and the Oracle Corporation after their aquirement of Sun.
