I had an install error saying it was not installed correctly and to restart and re-install. I did so and it kept giving me the same error and same message to reinstall. I did reinstall several times. Uninstalled the drivers and app and restarted and reinstalled drivers same error. Uninstalled everything took out card, rebooted, shut down installed card in different slot and tried installing/reinstalling the drivers several more times with the same error every single time.
Question for you. Do you reject the 'your computer needs to restart' during the installation?
I was having similar install issues on the Nu Pro, and I found that refusing to restart right then and there, and letting the buggy installer actually finish installing, I was able to get things installed.
