Creating ODBC connection in runtime

Hello All,

Hoping this is the correct place.

I want to create a ODBC for Firebird connection in runtime, I could make it,
provided the system has had the Firebird ODBC file installed. However I want
to make the users won't have to execute the installer, I just want to copy
the file needed by the ODBC, and my app will install them automatically.
The clean system complined about not registered in the Registry, when I
checked, it was there.
What I missed?

TIA,


HB
