Prevent tcResults1.mht from being displayed in browser at end of script execution

I found this thread, but this solution requires user interaction to setup TestExecute correctly.

What I need is a solution that does not require user interaction. Maybe a TestExecute installer switch or a registry setting I can modify with a script to achieve the same thing as the thread above achieves through user interaction.
