If you still have problems then there is an alternative installer. You just unzip it & use it. See
Here about other version.
Also try uninstalling your Java using the add/remove prog control panel. Then downld the Java installer & save it to your computer (don't install it over the net!) Then install Java. Try different versions of Java from 1.4.2 upwards. See:
