Setting Local Share and PDOXUSRS.NET installation

I'd like to be sure the local share is set for my application (Paradox) so
that my clients don't have to mess with the Database Administrator.  Is
there a way to do these two things using InstallShield 2.13 or in code in
the application?
1.  Put the PDOXUSRS.NET file in the directory with the rest of the database
(instead of the C:/ root)?
2.  Set the local share parameter to True?
