well i use wm wifirouter to tether via usb cable and i have no issues with my win7 64bit laptop. i know this is a different program than what you are using, but i wanted to note that when i plugged my phone in and selected to share my 3g via usb windows 7 installed a new driver for it, aside from what was needed to active sync. i can't recall if i had turned my wifi off yet on my laptop. but once it was installed and connected it worked great.

so if you have a internet connection on what ever your trying to tether to, see if you need that driver first, then try tethering. thats all i got. win7 has been night and day between xp and trying to get hardware recognized, haha
