Then you'll see a file called OOO320_m12_native_packed-1_en-US.9483OOo_3.2.0_LinuxIntel_install_en-US_deb.tar.gz
2 - You can remove the existing version of OpenOffice if you wish with this command:
3 - Copy and paste OOO320_m12_native_packed-1_en-US.9483 onto the desktop then open Terminal and paste this command:sudo apt-get remove openoffice*.*
