this is in resonse to malware high jacker.

the OP mixed 2 wireless mice and keyboard/ mouse technologies, this will never work
1: bad batteries
2: use the drives form logitech or Microsoft only.
3: use the correct receiver, (they have 2 mixed and is dead to rights WRONG that)
4: RTM read the manual. dah"?


the mouse is 2011
the keyboard 2400 has mouse too and is 2006 made
the cure is kick the old keboard to the curb and use any wired keyboard
and then connect only the receiver from that new 2011 mouse.
it will plug and play. ok. (but is VISTA so gee, maybe not)

my guess is old 2400 mouse died
and bought the wrong mouse, that well never work with the 2400 parts ever.(mixed technology wirless)

Try installing the latest version of Setpoint. Get it from the Logitech website.

select windows 7 and select setpoint 64 bit

Ths problem occurs because of usb drvier conflict issue with your usb wireless dongle driver. For that go to device manager uninstall all usb drivers then it will automatic install all driver. Then go to control panel->add remove program and features then uninstall your wireleless keyboard and mouse driver then reinstall. Then restart and check. Also try different usb ports of computer for connecting the usb wireless dongle of keyboard. Let me know if you need further assistance. Thanks for using FixYa.

Hello!

Usually when I install drivers for hardware I never use the CD that ships with the product. By the time the product has shipped, CD's that contain software for the product are usually outdated since hardware manufacturers are constantly updating software around the time of release and for awhile afterwords. Because of this, I like to go straight to the manufacturer website and download the absolute latest software/drivers for the hardware in question.

Here's a link below to both the 32-bit and 64-bit versions of the Windows Vista software for SetPoint. Depending on what version of Windows Vista you're running [32 or 64], choose the appropriate one and try installing that. If that doesn't work, visit Logitech's Support Website, choose your product, and download the appropriate drivers.

Downloaded Setpoint at http://www.neowin.net/news/software/07/06/06/logitech-setpoint-400-vista-only. Worked perfectly.

GO TO SETPOINT DIRECTORY. DELETE FILES: LULNCHR.INI & LULNCHR.EXE. FILES ONLY RELATE TO AUTOMATIC UPDATE FOR NEW LOGITECH SOFTWARE. DELETING DOES NOT EFFECT FUNCTIONALITY OF SETPOINT.
