I forgot about this post already
I instaled Open Office finally, and it even is loaded as the default.
You knwo what is good about it?? If you format your computer, or move the folder (I did both) you can just run the setup file there, so it register itself and it works flawlessly. No need to re-install it. Try to do that with M$ Office and it will give you thousand errors
I already tried.
So open office is a great option. I still have Installed Office XP (it came with the PC) just in case a file is not the same, but haven't had that problem yet (I do use Outlook thought)
