after a long search i found out this blue tooth adaptor is the only one with this range, and its one of the few that come with the required software. after following the directions to install you must reboot and go to device manager and click on update driver, then browse the cd for the driver, this is the only way to make it work because windows wants to use its own drivers instead of the ones designed for the device., . .this solution took me 7 weeks to figure out, but now it works perfectly.
