Hello, I successfully use wireless gaming reciever on my laptop which was upgraded from vista to windows 7 using windows 7 home premium edition 32 bit and wasn't straight away did device manager and sorted it,but now im trying to use it on my pc which has windows 7 ultimate 64 bit edition and tried device manager, updating and troubleshoot. Is it because its installed on laptop and driver is limited to being installed on one computer at a time or isnt it compatibale with this os or 64 bit,or is it something else
