Hi, thanks for the info. It seems you need to upgrade your 'installer'. Try this download here
Download details: Windows Installer 3.1 Redistributable (Out of the three downloads your needing the installer one). Once it's been updated try the Java download/install again.
Just a thought... What do you have your automatic update utility set at? If it's not set to automatically download and install updates you may want to change it. This can be accessed by the Control Panel.
