Activate Bluetooth

Hi there!

I have a new Latitude 6430u with Windows 7 32-bit installed. When I try to install a bluetooth driver there comes always the message "Activate Bluetooth using Wireless Switch". I tried to do this by putting the WiFi Switch on and off with no avail. This message has only a button with "Cancel installation"... WiFi is working though and in the BIOs Bluetooth is enabled. I have no idea what I could try next. Any ideas?

Thanks!!
