Question

I need to be able to create another brand new instance of a program on a button click while keeping the existing instance.

this.ShowDialog(new Form1());

The above statement causes the current form to be the owner of the new form and I need the second instance to be independent of the existing instance.

Can anyone help me with this?

To expound on Desolator’s answer here is a simplistic example you can try a Form and a Button:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Process p = new Process();
        p.StartInfo.FileName = Application.ExecutablePath;
        p.Start();
    }
}
