Hi

i need a way to set permission on a registry key where i have got not rights
to open it. But i am the owner (administrator).

The following code fails on OpenSubKey() with
System.Security.SecurityException: Requested registry access is not allowed

// ----start----
SetPermissions(){
String^ user = Environment::UserDomainName + "\\testuser";
RegistryKey^ openedKey;
 RegistrySecurity regSecurity = gcnew RegistrySecurity();
 regSecurity->AddAccessRule(gcnew RegistryAccessRule(user,
 RegistryRights::ReadKey,
 InheritanceFlags::ContainerInherit | InheritanceFlags::ObjectInherit,
 PropagationFlags::InheritOnly,
 AccessControlType::Allow));
 regSecurity->SetAccessRuleProtection(false,true);
 openedKey =
Registry::Users->OpenSubKey("S-1-5-18\\software\\testkey",true);
 openedKey->SetAccessControl(regSecurity);
 return 0;
}
// ----end----
