    Hi,

    Just also noticed you're using HKCU. Please note that this is a bad
    place to test since there is no separate 32 and 64 bit view of HKCU. You
    should test under HKCR or HKLM\Software. See
    http://msdn.microsoft.com/library/default.asp?url=/library/en-us/win64/win64/registry_redirector.asp

    Below is an example. It results in an ERROR_FILE_NOT_FOUND because
    SetNamedSecurityInfo is looking in the 32 bit view (i.e.
    HKLM\SOFTWARE\Wow6432Node\MyTest64BitKey). 

    ---
{
	ACL acl;
	HKEY hKey1;
	DWORD dispo;
	LONG result1;
	DWORD result2;
	
	// create an empty ACL
	acl.AclRevision = ACL_REVISION;
	acl.Sbz1 = 0;
	acl.AclSize = sizeof(acl);
	acl.AceCount = 0;
	acl.Sbz2 = 0;
	result1 = RegCreateKeyEx(HKEY_LOCAL_MACHINE,
		"SOFTWARE\\MyTest64BitKey",
		0,
		NULL,
		REG_OPTION_NON_VOLATILE,
		KEY_ALL_ACCESS|KEY_WOW64_64KEY,
		NULL,
		&hKey1,
		&dispo);
	result2 = SetNamedSecurityInfo(
		"MACHINE\\SOFTWARE\\MyTest64BitKey",
		SE_REGISTRY_KEY,
		DACL_SECURITY_INFORMATION | PROTECTED_DACL_SECURITY_INFORMATION,
		NULL,
		NULL,
		&acl,
		NULL);
	// result2 == ERROR_FILE_NOT_FOUND
}
