You don't need to manually load EnumSystemLocales. It's present on all supported
Windows versions, so the loader will handle it for you. You just need to call it
directly.

+      typedef BOOL (WINAPI *PfnEnumSystemLocales) (LOCALE_ENUMPROC, DWORD);
+      HMODULE hKernel32Dll = GetModuleHandleW(L"Kernel32.dll");
+      PfnEnumSystemLocales lfpEnumSystemLocales = (PfnEnumSystemLocales)
+          GetProcAddress(hKernel32Dll, "EnumSystemLocalesW");
+
+      if (lfpEnumSystemLocales)
+          lfpEnumSystemLocales(EnumLocalesProc, LCID_INSTALLED);
+    }

     g_target_services->LowerToken();
