How can I download the µC/OS-III add-in?

The page

provides download links for µC/OS-II, µC/OS-III, µC/FS, µC/USB. But when I click on the links, I don't get the expected download, but only an overview page about "Operating Systems and Middleware". How can I get the µC/OS-III add-in for CrossCore Embedded Studio? Isn't it recommended any longer?
