I agree with Richard: the file association determines what happens when
you double click the item in Windows explorer - it should have nothing
to do with how your program works.

I'd try and get the dbf from the user's computer if possible and analyze
that. If that is not possible, I'd add logging output to your program
(e.g. in a debug build mode) and ask the client to send you the log.
I'm sure others will have additional ideas...

Just for your information: note that there are some bugs open for the
.dbf code and the dbf code is currently unmaintained. You might want to
consider alternatives such as sqlite or Firebird embedded.
