Simple question about Registry CreateSubKey

Solution 1
You don't have write access to HKLM. If you want to write here then you need to either:
- run the process as an elevated user, or.
- only attempt to write to HKLM during install.
Solution 2
Try with this code:
RegistryKey regkey = Registry.CurrentUser;
regkey = regkey.CreateSubKey(SUB_KEY_NAME); //this is the path then you create yours keys
regkey.SetValue("Install", "ok"); //name of key exp:(install) and then the value exp:(ok)

Why doesn't this work? I am trying to create a registry key under [HKEY_LOCAL_MACHINE\SOFTWARE\MyService], but nothing is created.
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using Microsoft.Win32; namespace RegistryKey { class Program { static void Main(string[] args) { const string SUB_KEY_NAME = @"SOFTWARE\MyService"; // Create a subkey named MyService under HKEY_LOCAL_MACHINE. Registry.LocalMachine.CreateSubKey(SUB_KEY_NAME); } } }
Update: Never mind. I'm an idiot. I used the Remote registry Editor to inspect the registry in the belief that it would show the same as regedit. It didn't! I can see the path using regedit.
