On about the 3rd page of the package wizard, you have a additional keys
page,
you simply enter the above values there

eg:

ROOT  :Current User
Key   :Software\Microsoft\Office\12.0\Access\Security\Trusted
      Locations\Location1
name  :Path
Value :"C:\\Repairs Database\\"

ROOT  :Current User
Key   :Software\Microsoft\Office\12.0\Access\Security\Trusted
      Locations\Location1
name  :AllowSubfolders
Value :#00000001

note the use of "#" for dword values

so, just enter the values into the "additional registry keys" page. (there
is word wrapping in this newsgroup, but the above is the general idea....
