This installation is, as well as work on all NUC or laptop, not for Grobmotoriker. The tiny screws and connections are tiny, you have to know what you, and how does and should lose no screw in the housing. To connect the antenna I have the Internet and Intel searched and found little to nothing: White cable left or right, pin 1 or 2? In the manual of the NUC finally was a picture that explains the antenna connection.
Bluetooth installed under Windows 7 64bit without saying for the installation of the WLAN had to be downloaded and installed the drivers. Then everything was simple and worked perfectly!
