Exception occurs if you instantiate a EdgeDriver
My first guess based on experience is that you're running the incorrect version of MicrosoftWebDriver.exe.
The executable is built with Windows but ships separately and takes a hard dependency on being the same build as the OS it's running on.
You can find what build of the OS you're on by following these steps:
Go to Start > Settings > System > About and denote the OS Build.
The releases so far are:
- Windows 10 - TH1 - 10240
- Windows 10 Fall Update - TH2 - 10586
- Windows 10 Anniversary Update - RS1 - 14393
Next you'll want to visit Micorosoft's WebDriver page and choose the appropriate download: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
