Thanks Bob.

I do not know how to found this, becuase when I go to

http://www.wolfram.com/products/mathematica/index.html

and from there, I do not see a link to this "latest version" page, and that 
where I was stuck.

But thanks for the link, good to know there is a page there with this info, 
even though it seems unlinked from the main product page.
