The problem is not WinPcap. The problem is that, as far as I know, cygwin is 
32bit only. There is no 64bit port of it.

"As far as we know no one is working on a native 64 bit version of Cygwin"

The installer binary is 32bit, so it installs the uninstaller in program 
files (x86). But it does install both 32 and 64 bit components on a 64bit 
OS.

Have you asked the tcpreplay maintainers about that? WinPcap runs smoothly 
on a 64bit OS, but with in native 64bit mode and in 32bit compatibility mode 
(WoW64).

Have a nice day
