You're not giving us much to go on, I'll take a WAG. Finish the ATI Tools installation, it should still install the driver. Reboot, just after the BIOS finishes initializing and just before VISTA starts to load, repeatedly press the "F8" key to bring up the VISTA boot menu, then select the menu item "Disable Driver Signature Enforcement." After VISTA loads, you should be able to run ATI Tools.There are other ways to get around the driver enforecment issues in VISTA, google the issue generally. Check the ATI Tools forum at TechPowerUP!.com. The TileProxy forum here at avsim also has lots of posts on the Vista driver enforcement.
