Download Java if you need it If you already have Java installed then your Minecraft Forge download will have a Java icon and install when you double click on it, in which case you can skip ahead.

It’s not clear whether Java 7 is more for regular users or for developers at this point, because the Free Java Download link at java.com still takes users to Version 6 Update 29.

Windows users, who account for the bulk of Java’s installs, can update by clicking on the Java icon in the Control Panel, clicking on the “Update” tab, then clicking the “Update Now” button.
