Logitech said that it will launch 64-bit software for its mice and keyboards in June. Until the 64-bit release of Logitech's SetPoint software the peripherals will only operate at basic level within Microsoft's 64-bit Windows. You will be able to use them but advanced features such as special functions and mapping buttons won't work yet.
"Logitech's consumer mice and keyboards currently have plug-and-play functionality if used today with a 64-bit system, as supported natively by the Windows operating systems," Brinks wrote. "Logitech SetPoint software will be updated and available online beginning in June, giving our mouse and keyboard customers added levels of customization and button configuration. Also, we are in the process of updating drivers for many of our webcams so they can operate on 64-bit systems. These updates will be made available throughout the year."
