Hi ya mate
Dont know if this is the page you went to or not but have a look anyway.
http://www.java.com/en/download/installed.jsp to test your install.
I dont think im going to be much help really as you seem to have done all I would have advised.
Do you have Java web start in your list of programs ?
I guess it could have been a bad download, this has happened to me before when using the automatic install.
If I was you I would go to add/ remove programs and remove Java.
then go here
http://www.java.com/en/download/manual.jsp and select the windows (OFF LINE INSTALLATION)
which seems to be much more reliable, save it somewhere on your pc and then execute / install from there at a later date.
Let me know how you go, although im not sure I can be of much help.
Just letting you know what I would do. ;)
