WinPcap has no easy way to distinguish between XP64 and 2003-x64.

Wireshark itself does it by looking at the wProductType field in the OSVERSIONINFO structure filled in by 
GetVersionEx() - on NT 5.2, if it's VER_NT_WORKSTATION, and the processor architecture is AMD64, it assumes it's 
XP-for-x86-64, otherwise it assumes it's Server 2003.

It does similar things for NT 6.0 (Vista vs. Server 2008) and NT 6.1 (7 vs. Server 2008 R2).

However...

The newest release of WinPcap (4.1.2) will not show that system information 
panel any more.

...there's probably no need to display that information at all in the installer - the Wireshark installer doesn't.
