Acer 5830g bluetooth problem

[multiloop]

Hello,
I'm unable to install drivers for my bluetooth device. I have the latest driver "Bluetooth Atheros 7.2.0.60 W7x64".
A) If i run the setup, in the end it says installation failed.
B) If i open device manager, under Bluetooth Radios it says Unknown device. The error message is Reinstall the drivers for this device. When i point it to the Atheros driver it says the best driver already in place.
Help!

Also, as evident the driver i have is W7x64 but the windows 7 i have is 32 bit.
Is that the issue?
