As far as I know, there's only one version released. There are multiple languages, but they aren't really new versions. Its the same game, even the Supremacy name for the UK market. The other version would 1.01, a patch released through the LEC site. But that's still nothing different. So as well, I don't understand the question. Rebellion works fine on laptops, I know. Rebellion works fine on Windows XP, I know.
