How can I set this registry value from my installer

Question

In my .msi installer package, I have a C# custom action that writes a registry value in:

HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion         


        

Answer 1

Microsoft.Win32.RegistryKey key;
key = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("Names");
key.SetValue("Name", "Isabella");
key.Close();

Do you try this, here reference from microsoft

Edit:

            string strSID = "";
            string userName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
            NTAccount ntuser = new NTAccount(userName);
            SecurityIdentifier sID = (SecurityIdentifier)ntuser.Translate(typeof(SecurityIdentifier));
            strSID = sID.ToString();

            Registry.Users.SetValue(sID + @"\key", value);

Try this, you should probably read about Registry.Users.SetValue

You need:

using System.Security.Principal;

for this code.
