I don't think that there are drivers for Windows 7 x64. I have run many old devices though using XP mode, which you can download from Microsoft at no cost -- it is three files and they need to be installed in a specific order as explained in the directions on their site HERE
. It simply runs an emulated Windows XP in a program window and is pretty easy to use.
If you cannot run it off a USB port, you may need to add a PCIe COM port card to your motherboard.
