Do you mean that it uses the original WinPcap 3.1 installer, in any case?

Does the same thing happen with WinPcap 4.0? WinPcap 3.1 had several bugs 
regarding adapters listing that were fixed in WinPcap 4.0.

The sources of the WinPcap installer are not public, and we do not provide 
details on how the installer works.
If you absolutely need to repackage WinPcap within your application, you 
might also think of moving to WinPcap professional, details at


Finally, consider that WinPcap 3.1 is obsolete. We do not provide any 
support for it, it is still available on our website for archival reasons.

Hope it helps
