Java 2 SDK, Standard Edition, v. 1.4.2 is supported on Microsoft Windows Server 2003, Enterprise Edition and Datacenter Edition running on Intel Itanium 2 processors.
You should have 110 megabytes of free disk space before attempting to install the Java 2 SDK software.
For the full list of systems supported by 1.4.2, see System Configurations.
The Java 2 SDK for Windows 64-bit comes bundled as an executable file j2sdk-1_4_2_<version>-windows-ia64.exe. To install this version, use this file and otherwise follow the 32-bit Windows installation.
The Beta installer has a bug where it fails to remove temporary .pack files when it is done. The files are located in two lib directories; assuming the SDK was installed into C:\j2sdk1.4.2, you could manually remove them from:
C:\j2sdk1.4.2\lib\*.pack
C:\j2sdk1.4.2\jre\lib\*.pack
