I see nothing. No splash screen. The busy cursor spins for a second or so and that's it. If I run from a CMD window, there's no output either.
I did remove the "block" in the security properties and even re-downloaded with my anti-virus turned off, without any result. I also tried three different builds. I'm sure it's something odd in my system and not in your code, but I can't figure out what it might be! My next test is to try it on a different machine that is configured differently.
