It is important to know that you should not install Mouseworks on any PC running Microsoft Windows Vista or Windows 7. Mouseworks was exclusively developed to run under Windows XP and earlier versions of Windows. The Control Panel for Vista and Windows 7 does incorporate some options for input device configuration such as pointer speed adjustment, scrolling speed, and left/right button switch, however Mouseworks functionality such as button programming, fine tuning of acceleration et cetera are not supported.
