安装程序自定义操作的问题 - 不能写入注册键 [英] Installer Custom Action problem - can't write to register key

问题描述

在自定义操作编辑，我已经添加了自定义操作过程中安装和卸载阶段。在属性窗口中我已经标出CustomActionData属性为：

  / TARGETDIR =[TARGETDIR]
 

我希望以上通过安装目录信息到自定义操作。

自定义操作似乎被解聘，但我发现了以下错误消息：

错误1001无法写入注册的钥匙的（或类似的东西，我从我的本地语言翻译的话）。

我在做什么错了？

解决方案

尝试改变：结果
的RegistryKey键= Registry.LocalMachine.OpenSubKey（key_path）;

要：结果
的RegistryKey键= Registry.LocalMachine.OpenSubKey（key_path，Microsoft.Win32.RegistryKeyPermissionCheck.ReadWriteSubTree）;

In the Custom Actions editor I've added the custom action to Install and Uninstall stages of the process. In the properties window I've marked the CustomActionData property as :

/TARGETDIR = "[TARGETDIR]"

I'm hoping that the above passes the installation directory info into the custom action.

The custom action seems to be firing, but I'm getting the following error message :

"Error 1001. Can't write to register's key" (or something like that, I'm translating it from my local language).

What am I doing wrong?

using System;
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration.Install;
using System.Linq;
//using System.Windows.Forms;
using Microsoft.Win32;

namespace CustomActions
{
    [RunInstaller(true)]
    public partial class Installer1 : Installer
    {
        public override void Install(IDictionary stateSaver)
        {
            base.Install(stateSaver);

            const string key_path = "SOFTWARE\\VendorName\\MyAppName";
            const string key_value_name = "InstallationDirectory";

            RegistryKey key = Registry.LocalMachine.OpenSubKey(key_path);

            if (key == null)
            {
                key = Registry.LocalMachine.CreateSubKey(key_path);
            }

            string tgt_dir = Context.Parameters["TARGETDIR"];

            key.SetValue(key_value_name, tgt_dir);

        }

        public override void Uninstall(IDictionary savedState)
        {
            base.Uninstall(savedState);

            const string key_path = "SOFTWARE\\VendorName";
            const string key_name = "MyAppName";

            RegistryKey key = Registry.LocalMachine.OpenSubKey(key_path);

            if (key.OpenSubKey(key_name) != null)
            {
                key.DeleteSubKey(key_name);
            }
        }

        public override void Rollback(IDictionary savedState)
        {
            base.Rollback(savedState);
        }


        public Installer1()
        {
            InitializeComponent();
        }
    }
}

解决方案

Try to change:
RegistryKey key = Registry.LocalMachine.OpenSubKey(key_path);

To:
RegistryKey key = Registry.LocalMachine.OpenSubKey(key_path, Microsoft.Win32.RegistryKeyPermissionCheck.ReadWriteSubTree);
