Unexpected error launching Internet Explorer

Error Message:

Unexpected error launching Internet Explorer. Protected Mode settings are not the same for all zones. Enable Protected Mode must be set to the same value (enabled or disabled) for all zones. (WARNING: The server did not provide any stacktrace information)

Error message while launching IE browser. (using Selenium)

Solution:

The issue is something to do with the browser settings.

1. The browser has to be zoomed at 100%

2. In all 4 zones (Internet, Local intranet, Trusted Sites and Restricted sites), the "Enable Protected Mode" should be enabled.

Once enabled, click on Apply and restart your browser.

Now run the selenium script.
