I sent a reply directly to Rob by mistake...

Thank you, Rob.

I tried the workaround you proposed and it completely worked.
Since I also need to consider the possibility that an old version of
WinPcap is installed, I refered to the source code of Nmap-WinPcap
installer and implemented a logic to uninstall it beforehand.

For the time being, all of my issues are resolved and I'm very
satisfied but it's greatly appreciated if the installer is enhanced.

Thank you,

ebi
