Bluetooth driver for windows 7

when I am trying to install Bluetooth driver for windows 7 (BT_21.40.5_32_Win7) I am getting an error.
( The procedure entry point SetDefaultDllDirectories could not be located in the dynamic link KERNAL32.dll)

Actually, I want to play songs or videos from pc with the help of BlueTooth dongle via bluetooth supporting speaker.
