Hi Sof123, Inspiron 1545 system has not been tested with Windows 8. Windows 8 drivers for this system are not available. You can refer to the link for a compatible system tested by Dell with Windows 8 [URL] You may try to install the driver in compatibility mode. It might work. Hope this helps.
I recently upgraded to Windows 8 Pro but now the scroll on my Dell touchpad doesn't work anymore.  I am using a Dell Inspiron 1545 - have checked the Dell website for touchpad drivers but cannot find any for Windows 8....   Can anyone help?!
