Click 'Download' button, it will lead you to http://ati.amd.com/support/driver.html. There choose your system (mine, for ex, is windows XP professional)then choose 'Radeon'(or 'Mobility Radeon' for notebooks) and then you may choose any of the drivers you will see (for me they are almost the same). So you will be redirected to a page with Cthe links. There may be 2 variants: you see two download links, one is for the package including ATI Catalyst Control Center and another is for Display driver only. Or you will be redirected to a page with a download link for the package only. So then you just need clicking 'Catalyst Software Suite' and finally you will get ATI Catalyst Control Center.
