C # Set Registry Value throws UnauthorizedAccessException

Question

I have a C # application and I'm trying to edit a service through the registry. I am using a manifest file that requires administrator privileges to run my application. Despite this, this code raises a System.UnauthorizedAccessException: Cannot write to the registry key :

 RegistryKey key = Registry.LocalMachine.OpenSubKey ("SYSTEM\\CurrentControlSet\\services\\Tomcat7"); key.SetValue ("Start", 2, RegistryValueKind.DWord); 

Does anyone have any ideas how to fix this?
