You checked for the presence of Java on your computer. In case you did not find it, we will install it in the next section.

Did you note the 32-bit string in the Java icon? Indeed, you may download and install Java with two different packages: 32-bit and 64-bit. If you are running a 64-bit operating system, you can select one of them. Using the 64-bit flavor will allow you to use the RAM available on your machine more efficiently and make a larger portion of it available to GeoServer.
