For some M$ reason, one version will work fine on some people's systems but not the other version. So I'd suggest you uninstall Java using your Add/Remove control panel. Then downld Java 1.4.2 installer to your computer & then install it. Don't install it over the net!!! For a link to Java 1.4.2 see my link above, it has a link to it.
(Java sometimes gets corrupted installing over the net.) |
