|I would think so. It won't hurt to try. Alternatively you can download the service packs and IE versions here:|
Then burn them to a cd on the computer you're using now and then install on the XP sp1 computer.
When I did xp installs using an old disk I'd do the initial install, then sp2, then ie7, then sp3. Then when I started using IE8 I'd install it on top of IE7 but you may be able to go directly from ie6 to ie8.
You might want to check the discussion here:
and my # 6 there about the cumulative security update for IE8.
