For Windows XP and 2000 users: If you were using Logitech MouseWare with a Cordless Click! or a Cordless Click! Plus mouse, installing SetPoint on top of MouseWare will transfer control of your mouse from MouseWare to SetPoint. MouseWare will no longer recognize your mouse. If you were only using one mouse with MouseWare, you can now uninstall MouseWare and use SetPoint.
Please view the Readme File located on your system at C:\Program Files\Logitech\SetPoint.
