I have no clue how to do it the way you want to but I think the easiest thing for mass installs is to just compile an upgrade program and then install it on the nework server with the appropriate permissions as a setup exe. That way all the users who require the changes can just do an install of the new front end from the server. Shouldn't effect the database even if something goes wrong, so should be suitable. And it saves you the hassle of tweaking 200 computers. Hope that helps some,
