Never mind, I search up the generic bluetooth adapter driver files in the system and removed them, so they stop reinstalling, then i got my driver installed.
But thx for your answer!

When You remove Genric Bluetooth Adapter from device manager it automatically gets back when you restart
So go ahead and download Drivers of Toshiba Bluetooth Drivers for Windows 8
Thats the only way to solve your problem
