I have successfully installed the drivers on a Windows 7 64 bit machine . What exactly is the problem you are having.?
It’s worth noting that the download from Accusports website has 3 different drivers all created at different dates .The latest one which is 64 bit was realeased in 2011 I believe , it’s could be just a case of locating it. Sorry I can’t be more specific I’m not near my laptop , let me know if you need more help.
