If WinPcap is already installed, then the Wireshark portable shouldn't
even need to install it itself and it should work like a normally
installed Wireshark. Even if WinPcap isn't installed, Wireshark
portable just runs the standard WinPcap installer which should set
things up correctly.
However, I haven't run Wireshark portable on Vista - I'll have a look
and see if I can fix the problem.
