Bluetooth Device drivers are not getting installed

I am using Inspiron 15 3521 Laptop with Windows 7 64 bit Ultimate. Bluetooth has been a concern for me from the day i got windows installed. Bluetooth is working fine with Ubuntu. 

I have tried updating driver several times but the issue continues even after the network driver was updated. Bluetooth devices are sometimes not getting detected. Even if it gets detected, drivers for the Bluetooth device is failing to get installed.
