推荐答案

在这种情况下，您可以使用自定义操作.
1.将Installer类添加到项目中.
2.创建一个表单，让用户输入密码. FrmPassword的代码如下.

You can use custom action in this case.
1. Add an Installer class to the project.
2. Create a form to let the user input password. The code of the FrmPassword is as follow.

public partial class FrmPassword : Form
    {
        private Installer1 install;
        public FrmPassword(Installer1 installer)
        {
            InitializeComponent();
            this.install = installer;
        }
        private void btnOk_Click(object sender, EventArgs e)
        {
            if (textBox1.Text != "12345")
            {
                MessageBox.Show("Password incorrect!");
                install.isValid = false;
            }
            else
            {
                install.isValid = true;
            }
            this.Close();
        }
    }
//Override the OnBeforeInstall method like this.
[RunInstaller(true)]
    public partial class Installer1 : Installer
    {
        public bool isValid = false;
        public Installer1()
        {
            InitializeComponent();
        }
        protected override void OnBeforeInstall(IDictionary savedState)
        {
            FrmPassword frm = new FrmPassword(this);
            frm.ShowDialog();
            if (this.isValid == false)
            {
                throw new Exception("Force to rollback!");
            }
            base.OnBeforeInstall(savedState);
        }
    }

isValid成员将记住输入的密码是否正确.密码正确时，FrmPassword会将isValid设置为True.如果isValid为false，则安装程序类将抛出错误强制回滚.

The isValid member will remember if the input password is correct. When the password is correct, FrmPassword will set the isValid to True. If the isValid is false, the installer class will throw an error force to rollback.
