not long ago when I used to have to use Open Office to get anything to view; it was way easier than going to the MS site to download all those darned converters . Surprisingly after I got Vista x64, I've never had to go to the MS site to get a "converter" for office documents again. I just use the crapware Works that came with the PC myself. I do recommend Libre now, for many of my clients who are having difficulties. I can't remember if it runs on a Mac - maybe on the old RISC architecture?
