WinPcap: the Free Packet Capture Architecture for Windows


Last modified: Thursday, September 20, 2001 13.58


WARNING:
you must uninstall older versions (see Q-2 in the FAQ to know how) before installing the new ones, otherwise WinPcap will not work properly.

IMPORTANT NOTE: sometimes, when uninstalling WinPcap version 2.02 or older from the control panel's network applet in Windows 9x, the file Windows\Packet.dll is not deleted. You must delete this file manually, otherwise newer versions will not work properly and could cause system crashes.
