Are there any previous supportable versions.

Scroll down on the linked page and check "other versions" on the left.

The "Operating System is not supported" message is used as a catch-all for any error occurring during the installation process. What you need to do is uninstall any existing Intel HD Graphics driver (followed immediately by a reboot) and continue this process until only the Microsoft Basic driver is reported as in use. Then install this 'new' driver package.
