Hello, Thought I would let you know I downloaded the ATITool_0.26. Windows 7 requires a digital signature for the 64bit system and this did not work. I see there may be a .27 coming soon so I will try it out.

After installing I get an additional message when trying to load the program; "The Kernel Mode Driver does not seem to be running.

A device driver is required for the communication with your video hardware.

If you just upgraded from the older version it may help to uninstall ATITool, reboot, then install the new version."

I received the windows message about the need for a "Digitally Signed Driver" during install but don't remember it's exact phrasing, it did state that this "Digital Signature" is "Only Required by Windows 7 64bit systems" So I assume it works on Windows 7 32bit just fine.
