WAS 3.5x PTF install fails when PKZIP is used on Windows

Technote (FAQ)
Problem
The following error is seen when attempting to install WebSphere Application Server 3.5.5 or 3.5.6 STD edition on a windows NT or 2000 platform.

"Failed to load Main-Class manifest attribute from was35_std_ptf_6.jar
Exception in thread "main" java.lang.NoClassDefFoundError: IPlanet6Support
Could Not Find c:\websphere\appserver\IPlanet6Support.class"
As a result, the PTF installation fails.
Cause
This problem only occurs if the PKZIP v2.04 G , 020193 utility is used to extract the was35_std_ptf_x.jar file, prior to running the install script (install.bat).

The same was35_std_ptf_x.jar file installs correctly if WINZIP is used to extract the install files, prior to performing the installation.

Solution
Use WINZIP to extract the was35_std_ptf_x.jar file, prior to running the install.bat
