I am running Windows 7 Professional (64-bit) and want to connect my Marantz RC9500 to it. I was able to install Wizz.it 9 after installing Windows XP mode and was able to get Wizz-it to function ok. The problem I now face is that my PC will not recognise (install the driver) when I connect the USB cord. I am guessing the driver is only for 32-bit PC's. Does anyone know of a solution to this? Is there any 64-bit driver available or any other way to make the RC9500 work with a 64-bit operating system?
