Ok,

Try to click on "Let me pick from a list ...."

Click on "Have Disk..."

After that you select the nordic_cdc_acm_example.inf file in the SDK usb_drivers folder. Click on "OK":

And after that click on "Next".

1) What version of DK do you have?
It should be brinted below PCA10056 on the white sticker.

2) Could you try a different USB cable and another USB port on the PC ?
