You need to buy the Microsoft Visual Studio Tools package.  This includes the
Microsoft Access 2003 Developers Extensions.  This software includes a
package wizard that works very well.  It will build a install routine for
you, as well as give you the option of including the Access Runtime version
for people that do not have Access 2003.    The software is $500.  I just
bought it last week and am doing the same thing you are.  You will also run
into some security issues when you try to open the database on the new
machine.  Access displays some "unsafe expressions" and other security
warnings.  To get around this you will need to put two registry keys into
your install routine.  The wizard will do it for you.  I have put the entries
you need below.  I got them from a guy named Paul who helped me over the past
couple of days.  Hope this helps.
