I am using Dell Studio 1558 laptop. Originally it was having windows 7 64 bit Home edition but than i upgraded my system to Windows 7 32 bit Professinal edition. The problem i am facing due to this is that my system is not detecting bluetooth adapter. When i install 64 bit(windows 7)/32(windows vista) bit drivers for Bluetooth it detects the Adapter but only sometimes and much of the times it doesnt. I am not able to find drivers for Windows 7 32bit professional edition and thus not able to detect bluetooth adapter.
