Geckofx45 C# Does not work on another computer

Question

I installed Gecko in my visual studio! on my pc it works normally.

already tried to send to a friend of mine and to my virtual pc more does not work from the print error. Both had dependencies of . NET so much so that by removing Gecko from the application the form opens normally

in print have my pc and virtual pc! on my pc opened the form, on virtual pc gave error

public FormLogin()
    {
        var programDirectory = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
        Xpcom.Initialize(Path.Combine(programDirectory, "Firefox"));
        InitializeComponent();
        //MessageBox.Show(Path.Combine(programDirectory, "Firefox"));            
    }
