An error occurred while installing the NPF driver (0x00000430).

This error occurred while installing WinPcap, which comes bundled with Wireshark (a network protocol analyzer):

Error

WinPcap 4.1.2 Setup
An error occurred while installing the NPF driver (0x00000430).
Please contact the WinPcap Team including the file C:\Program Files\WinPcap\install.log.
The installation will now continue anyway

The older WinPcap 4.0.1 produces a similar error:

An error occurred while installing the NPF driver ( -1 ). Please contact the WinPcap team

This is the install.log:

WinPcap 4.1.0.1753 Installation LOG
—————————————————–
Debug Information

Operating system detected on registry: XP – x86
True operating system (kernel.dll): XP – x86
npptools.dll present on the system: true
netnm.inf present on the system: true
nmnt.sys present on the system: true

End of log
—————————————————–

Effect

The error causes Wireshark to fail: Wireshark did not show any network interfaces, so it cannot capture network traffic.

Troubleshooting and solution

First, check your antivirus. My McAfee antivirus log indicated it didn’t block WinPcap, but the corporate policy didn’t allow me to disable it. If your antivirus has an option for game mode, try the game mode. Otherwise, try disabling the antivirus.

If that doesn’t work, reboot Windows into safe mode: while Windows is starting, press F8. Then, choose Safe Mode (no networking) and login as an administrator. While in Safe Mode, install WinPcap normally without any errors. Then reboot Windows and continue normally.

Environment

Tested with:

  • Windows XP Professional SP3
  • WinPcap 4.1.2 (WinPcap_4_1_2.exe)
  • Wireshark 1.2.10 (wireshark-win32-1.2.10.exe)
