Using GetValue on HKLM to get a string value

See more:

registry

I am trying to use GetValue to pull a string from a subkey in the reg the below code works fine for HKLU but the same code for HKLM gives permissions errors. I am logged in as admin and the keys exist in the reg.

Works

RegistryKey rkCurrentUser = Registry.CurrentUser;
RegistryKey rkTest = rkCurrentUser.OpenSubKey("Software\\Medcon\\Settings\\Database", true);
string tom = (string)rkTest.GetValue("Database Name");
textBox1.Text = tom;

Does not work

RegistryKey rkLocalMachine = Registry.LocalMachine;
 RegistryKey hostName = rkLocalMachine.OpenSubKey("Software\\Medcon\\Settings\\Database", true);
 string tom = (string)hostName.GetValue("Database Name");
 textBox1.Text = tom;

Apologies I am learning to program from the net and have no formal qualifications.

Cheers Tom
