C# Create Values in Registry Local Machine

Question

This is not working for me:

public bool createRegistry()
{
    if (!registryExists())
    {
        Microsoft.Win32.Registry.LocalMachine.CreateSubKey("Software\\xelo\\");

        Microsoft.Win32.Registry.LocalMachine.OpenSubKey("Software\\xelo").SetValue("hostname", (string)hostname, Microsoft.Win32.RegistryValueKind.String);


        return true;
    }
    else
    {
        return updateRegistry();
    }

}

The exception error is to do with Not Authorized to do this. Any Help would be apreaciated

Exeption: System.UnauthorizedAccessException | "Cannot write to the registry key"

Answer 1

Non-admin and unelevated admin users don't have rights to modify the HKEY_LOCAL_MACHINE key. Run the program 'as administrator'.

Answer 2

Well you've got your answer already - I'm guessing you're running on Vista or Windows 7 (or Server 2008) and the process/user running the app doesn't have rights/permission to modify the registry.

So its not a code problem as such but a systems admin one. Build the app and run as administrator and see if that works.
