use your brain dude... don't u use utorrent or bittorrent to download the movies..... if so, then search for ms office in this torrents, you'll get full version.....

http://www.torrentz.com/

try that link and search for Microsoft office, if u don't have any torrents installed in your pc then first download bittorrent from download.com and install it and enjoy downloading whatever u like....

caution: i don't know where u r, but first inquire with your friends if p2p downloading is legal or not......
