how to install 32bit driver for x64 system

because the driver for usb Kingsun KS-959 IrDA there is only 32bit version.

Yup - dont think you can do that.

let win/driver update search for one - maybe you are lucky

You could try to let Windows Update locate the driver automatically for you or check the manufacturer's website for 64-bit drivers.

Should you require additional assistance and guidance, Microsoft does have an official Windows 7 Support Forum located here http://tinyurl.com/9fhdl5 . It is supported by product specialists as well as engineers and support teams.
