I purchased the bluetooth - usb MANHATTAN adapter, model 179010 (I've bought it in a store, not online). I have windows 7 professional 32 bit. The installation cd provides ivt 2.7.0.13 software: i doesn't work (bluesoleil doesn't start). Manhattan site provides Bluesoleil 6.2.227 software; it doen't work (bluesoleil doesn't start). With Bluesoleil version 8 it is ok but i have not the serial number and I don't want to purchase it because I have already purchased the adapter.
