firstly i upgraded windows 7 professional x64 to windows 8 x64
my bluetooth device is working in wind 7 correctly
but after upgrading my OS to win 8 the bluetooth on my computer or in taskbar is desappeared
i tried to re install driver of bluetooth's HP-g62 again
but it's incompatibility with win 8 x64
so i clicked right on application's driver then choose properties then choose compatibility win 7
then restart my laptop
and my problem isn't solved........
