J2sdk-1_4_1-windows-i586.exe corrupted (cannot unpack)

Question

I cannot install j2sdk 1.4.1.
First I downloaded it from http://java.sun.com/webapps/download/DisplayLinks
"You have chosen to download Java(TM) 2 SDK, Standard Edition 1.4.1
Download j2sdk-1_4_1-windows-i586.exe .
Filesize = 37,724,482 bytes."
to
c:\Downloads\j2sdk-1_4_1-windows-i586.exe 37,724,482 bytes
Correct number of bytes.
Double-clicking on this file brings up a dialog with title
"Java 2 SDK - InstallShield Wizard"
with a progress bar labelled "Reading contents of package..."
The progress bar reaches 100% and then starts from 0 again. Shortly after, the dialog is replaced with an error dialog stating:
"The contents of this file cannot be unpacked. The executable you are attempting to run has been corrupted. Please obtain another copy of the file, verify its integrity, and try again."
This is the third time that I have tried to install the Java 2 SDK and each time I have had the same result. Each time the downloaded file has had the correct number of bytes. There are many posts here describing the same problem, but I have not seen one that has a universal solution.
It seems to me that the problem is to do with the installation environment:
Operating system: Windows 95 Copyright 1981 � 1996
Pentium MMX 166 MHz, 64 MB RAM, 3GB unused disk space
J2SDK-1_4_1-WINDOWS-I586.EXE Dependencies:
File Version
ADVAPI32.DLL 4.71.118.0
COMCTL32.DLL 5.81.4807.2300
GDI32.DLL 4.0.0.950
J2SDK-1_4_1-WINDOWS-I586.EXE 2.11.15.0
KERNEL32.DLL 4.0.0.1111
LZ32.DLL 4.0.0.950
SHELL32. DLL 4.0.0.1111
USER32. DLL 4.0.0.950
I have 2 versions of InstallShield installed. I think that the problem is with my operating system or my InstallShield installations. Anyone know the solution?

Answer 1

Window 95 is not supported for this version and you are at the ragged edge as far as processor speed.
This is the beginning of the installation instructions that are on the download page:
"System Requirements
The JavaTM 2 SDK is supported on Microsoft Windows 98 (1st or 2nd edition), Windows NT 4.0 with with Service Pack 5 or later, Windows ME, Windows XP, Windows 2000 with Service Pack 2 or later, running on Intel hardware. In non-English locales, the only edition of Microsoft Windows 2000 tested with this release is the Professional edition.
Note -- Trying to install the Java 2 SDK on a non-supported version of Microsoft Windows or on a machine that doesn't have a sufficiently up-to-date Service Pack will cause the installer to generate this warning: "We recommend that you do not install this Java(TM) Platform for the following reasons: This Java(TM) Platform does not support the operating system or operating-system service pack on this machine."
A Pentium 166MHz or faster processor with at least 32 megabytes of physical RAM is required to run graphically based applications. Forty-eight megabytes of RAM is recommended for applets running within a browser using the Java Plug-in product. Running with less memory may cause disk swapping which has a severe effect on performance. Very large programs may require more RAM for adequate performance.
You should have 120 megabytes of free disk space before attempting to install the Java 2 SDK software."
