Bug Description:

There are a number of issues with the installer.

Use the MSI file extracted from the binary to upgrade Java on multiple machines.
And find that is in about 10% of the installations, the MSI installer would
failed to extract the binaries and the installation would leave System JRE.

Attached a number of relevant MSI installer logs that demonstrate the problem,
and most of this seems to have caused by failure to delete the msvcr71.dll
as well as Java Quickstart process is not being killed by the installer.

Not an expert in Windows MSI technology but our Windows Engineering team has
suggested that instead of using your own unzipping code all the extraction
should be done by MSI engine, which would allow atomic rollback as well
as installation after reboot.
OS = Windows XP (JQS is N/A for any other supported platform).
