[wlug] Installing Open Office 3.0

hi there all I have just downloaded Open Office version 3.0 (64bit) onto my acer (Im running Ubuntu 8.04 Hardy). I was expecting a program that would install the applications on my computer but there wasn't one. I attempted to run synaptic Package Manager to pick up the downloaded DEBS packages, but it doesn't appear to have recognised the newer packages, only the older 1:2.4.1 packages. There is a update script, but I cant even begin to understand it. Is there anyone who has experienced this? Glenn Morrissey.
