You cannot grant such access programmatically - virus writers would have a field day if you could!

If your users really, really, really need to have the templates with the userforms in their startup folders, either you'll have to send them the new files, with instructions on how to replace the files - perhaps even a macro to do the file copying - (forget module updating), or have a System Administrator (or someone else with suitable privileges and know-how) do the file replacement.
