BtvStack.exe - System Error

I have Aspire 5750G with windows server 2012 r2 installed as standalone OS. It comes with bthprops.cpl missing error when reboots. I once forced shut down the machine and I think this error is coming ever since. Here is a snapshot of the errror.

I find BtvStack.exe at C:\Program Files (x86)\Qualcomm Atheros\Bluetooth Suite but it does not execute (as it happens). I read somewhere that it is a bluetooth error (blah blah) but i cannot find any bluetooth icon in tray or in device manager where we see drivers for many hardware.

I have run sfc /scannow command and microsoft windows malacious software removal tool but nothing good.

Registry Editor is showing the following situation.

Attempt 1

"Go to a Windows 7 computer.

Go to C:\Windows\System32

Copy all the BlueTooth files which begin with BT so bt*.* to a USB drive.

Copy all the file from the USB drive to C:\Windows\System32 on your Server 2008 computer.

If you are copying a file that already exist, click DO NOT COPY.

Log off the computer and log back on.

The error message should no longer appear."
