Dell Wireless 375 Bluetooth Drivers for Latitude E6510. Win 7 x64.

I need working drivers for Dell Wireless 375 Bluetooth Drivers for Latitude E6510 on Win 7 x64, so I can connect my bluetooth headphones.

On Windows 8 and 10 when I do fresh installation stock drivers are good and everything works fine.
But in Windows 7 stock drivers and also drivers v.6.3.0.3102, A02, v.6.3.0.7900, A05 & A04 v. 6.3.0.6900 don't offer any functionality for my bluetooth headphones and for my phone. Problem is that I can't work on WIN 8 or 10 because notebook isn't stable on these OS.

My device ID is: 

USB\VID_413C&PID_8187&REV_0517
USB\VID_413C&PID_8187

I tried to transfer drivers from WIN 8 & 10, but with no luck.
