Spark 1.1.3 installation problem in Windows 2000 Pro

I’'m trying to install Spark-client 1.1.3 on a Windows 2000 workstation. After few dialogs there is a error message:

An error occurred:

java.lang.NumberFormatException: null

Error log: c:\tmp\install4jError31010log

Here is that .log-file:

After that the installation stops.

Any ideas? I’‘ve tried both packages but it’‘s the same thing also I did install the JRE again but that didn’'t help at all.
