Reflector 3 not working due to Duet being installed

Recently, I had to install Reflector 3 on a Windows Surface Pro laptop to resolve an issue presenting in a classroom. Unfortunately Reflector 3 would not work for me after installing. All I could see was a blank window.

The issue was sue to Duet being installed on the Surface Pro. Removing Duet, rebooting, then reinstalling Reflector 3 fixed things. Thanks to Squirrels support for suggesting this.
