When you click the Bluetooth item in Control Panel on a computer that is running Windows Vista Service Pack 2 (SP2), the Bluetooth item does not work as expected. Therefore, you cannot set up a new Bluetooth device. Similarly, you cannot view or edit the settings for an existing Bluetooth device.
This issue occurs if you install third-party Bluetooth software on your computer and then you install Windows Vista SP2.
Note: When this issue occurs, you may have two Bluetooth items in Control Panel. One of these items is the Bluetooth item that was installed by the third-party Bluetooth software, and the other item is the default Bluetooth item for Windows Vista. You should ignore the default Bluetooth item.
