Here is a download of the FreeOffice sfs (latest 2012 version - ENGLISH ONLY):
After loading the sfs (on-the-fly by clicking, or by rebooting), find the /freeoffice directory in /root (your default directory).
In new Puppy versions (4 and up), you can click on the file to open it, copy the freeoffice directory wherever you want (as long as it is a Linux filesystem), find the shortcuts freePRSN, freeSPSH and freeTXTM (in /freeoffice) and drag them to your desktop. Note that some Puppy versions will ask if you want to use the sfs right away (this is the same as mounting sfs with bootmanager), and you can answer 'Yes" then find freeoffice in /root.
To register with your free license (obtainable from freeoffice.com), delete /freeoffice/.softmaker (a hidden folder) and run any of the freeoffice programs.
