This is copied from another forum that i posted this in. I hope it helps you out.
***UPDATE***
I finally got the Anycom Bluetooth adapater and I have to say it works like a charm with the beta drivers. so if ya want blue tooth for your 64 bit computer then I highly recomend you read my article below and buy yourself an ANYCOM Blue USB Adapter USB-250 (2.0).
***UPDATE***
I just recently purchased a a bluetooth adapter from anycom and it should arive today so i will let you all know if it works or not. the reason i went with anycom is that i found that they have beta bluetooth drivers and those drivers offer alot. plus the drivers also support windows 98 so anyone that will still support that old OS will most likely support Win XP 64 for a very long time.
you can check out the bluetooth adapter here.
