SecurityException

[Chuck B]

I'm trying to run a modified version of the example in this Microsoft
article:
http://msdn.microsoft.com/library/d...n32registrykeyclassopenremotebasekeytopic.asp

The only changes I've made to the code is that instead of using
"HKEY_CURRENT_USER\Environment" as my registry path I'm using
"HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows" and setting
OpenRemoteBaseKey to open RegistryHive.LocalMachine instead of the
CurrentUser.

The problem is that I keep getting a SecurityException. I've tried inserting
the code below inside the try block but with no apparent effect

// ****************************

SecurityPermission sp =

new SecurityPermission(SecurityPermissionFlag.UnmanagedCode);

sp.Demand();

// ****************************

Anybody got a clue what's wrong and what I can do to fix it?

Your problem is windows security related not CAS rlated.
You must run your code while impersonating a "remote system" administrator,
only administrators can access HKLM.

Ok thanks. Does it make any difference that I set myself as a user with
control permissions on every key in the path that I'm trying to access?
