在自定义操作编辑器中,我已将自定义操作添加到流程的安装和卸载阶段。在属性窗口中,我将 CustomActionData 属性标记为:

/TARGETDIR = "[TARGETDIR]"

我希望以上将安装目录信息传递到自定义操作中。

自定义操作似乎正在触发,但我收到以下错误消息:

“错误 1001。无法写入寄存器的密钥”(或类似的东西,我正在从我的本地语言翻译它)。

我究竟做错了什么?

using System;

//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();
        }
    }
}

尝试改变:
RegistryKey key = Registry.LocalMachine.OpenSubKey(key_path);

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