c#，自定义安装，部署，创建自定义操作，自定义操作，安装验证，数据库，安装授权码，接收输入，判断 Virus

最近做一个项目的安装部署程序，要求有安装的验证，安装的授权，要输入授权吗才可以安装，禁止非法安装。
一开始看见用户界面不错，可是添加了用户界面不能控制他，只能接受输入，然后根据输入创建数据库，修改配置之类的东西，网上的资料也多是这类型的，我就自己写了一个，还不是不太满意的，这些窗体都是在安装的过程中弹出来的，我本意是想在安装之前就验证这些内容，可是弄不出来，不知道大家有没有什么好的办法。





这是需要验证的两个部分，两个自定义的窗体，代码如下：
installer类的代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration.Install;
using System.Windows.Forms;

namespace FactorySetupClassLibrary
{
    [RunInstaller(true)]
    public partial class Installer1 : Installer
    {
        private string dbServer;
        private string loginUser;
        private string password;
        private string db;

        public Installer1()
        {
            InitializeComponent();
        }
        public override void Install(System.Collections.IDictionary stateSaver)
        {
            base.Install(stateSaver);
            //AuthorizeForm1 authForm = new AuthorizeForm1();
            //authForm.ShowDialog();
            DBForm1 dbForm = new DBForm1();
            if (dbForm.ShowDialog() == DialogResult.OK)
            {
                
            }
            else
            {
                throw new ApplicationException("应用程序安装失败");
            }
