AMD/Intel 32-bit Platforms
For both the JDK and the JRE, the user is given the option of installing
various features. For the JRE the features are the following:
Feature 1: Java Runtime Environment
Feature 2: Support for Additional Languages
Feature 3: Additional Font and Media Support
For the JDK the features are the following:
Feature 1: Development Tools
Feature 2: Demos
Feature 3: Source Code
Feature 4: Public Java Runtime Environment
Notes:
- For the JDK the installed image consists of all the files
installed under the directory
jdk1.6.0; for the JRE
it consists of all files installed under the directory jre1.6.0.
The update repository consists of zip files for the various
features. They are stored under Program Files\Common Files\Java\Update
and are used for the purpose of updating or modifying the JDK
or JRE.
- The installed image will, by default, be installed on the Windows
drive—the drive where the Windows operating system is
installed (sometimes called the system drive). Most often
this will be the C drive. However, it is possible to install the
installed image on any drive. For instance, the installed image
for the JDK could be installed to a non-Windows drive with a custom
installation.
- The update repository will always be installed on the Windows
drive.

In addition to the disk space required for the installed images, there
must be sufficient disk space for the update repository, located in the
Program Files\Common Files\Java subdirectory. The table below
