Bluetooth on Windows 8 cant work on my lap HP-G62

Question

hi 
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........ 

thanks
