There's really no such thing as "converting to run time".
You can go a long way to achieving this by going to Tools | Startup in the
menu, setting the form to be displayed when the application starts, and
unchecking the "Display Database Window" box. If you want to prevent your
users from changing any of the forms, reports or code, distribute your
application as an MDE, not an MDB (look under Tools | Database Utilities)
Just to be clear, your users will have to have Access installed, although
there is a royalty-free run-time version of Access that you can distribute
with your application. If they don't already have Access installed, you can
install the run-time, and they'll then be able to use your application.
Note, though, that this does not change your application in any way, shape
or form.
