I'm trying to get a simple LED blink program running on an Arduino UNO from Atmel Studio 7 on Windows 10. I have the 6 pin ISP connector from the ICE connected to the UNO board, have it powered on, and have the ICE selected as the programmer tool in the IDE. I have the interface selected as "debugWire" (other choice was ISP). When I hit the "Start Debugging and Break" menu option I first see the dialog asking to use SPI to enable the DWEN fuse. I select yes to this. I then get the "Failed to enable DW" error message as shown in the screenshot.
Can anyone advise what is going wrong?
