Visual studio 2015 Intellitest not working on 64bit projects

I am trying to run intellitest on x64 project (for that matter i even tried to create simple 64x project)

public class Program
{
    public static void Main(string[] args)
    {
        if(args == null)
            throw new Exception("test");
    }
}

but for some reason all i get in intellitest output is

saving all files
building project
Launching exploration
starting...
