One of our OEM licensee used their Windows Vista(Japanese) to access the following page
to install jre 6.0 via online.

http://www.java.com/ja/

They got a failed message I attached and could not install further.

The error message(attached, ) is Japanese and I translated it into English as
described below.

-----
The args at command prompt are invalid. Please refer to Windows
installer SDK for detailed help of the command line.

They can successfully install JRE 6.0 offline.
It seems that the problem exists in the JRE online installer.
