[Winpcap-users] Windows 7 Pro x64 RE Install Fails

[Black, Michael (IS)]

Googling the error finds this:



Q-30: The WinPcap installation fails with the error message "An error occurred while installing the NPF driver ( -1 ). Please contact the WinPcap team".

A: This error is usually caused by an antivirus or antimalware software that incorrectly detects the WinPcap kernel driver (NPF) as malware. This is because in the past some malware tools have been developed over the WinPcap library.

The workaround is to disable such antivirus/antimalware programs while installing WinPcap.

Windows 7 Pro x64
Had Wireshark and WinPCAP installed and working.
Downloaded latest Wireshark and WinPCAP.
Have Uninstalled, Deleted, Run Revo Uninstaller etc. etc. but the same
problem keeps occurring and I can't successfully install WinPCAP:

The WinPCAP 4.1.2 Setup Errors opening file for writing:

C:\Windows\system32\Packet.dll

Retry hits the same error.
Ignore yiels: An error occurred while installing the NPF driver
(0x00000430)

Install.log:

WinPcap 4.1.0.2001 Installation LOG
-----------------------------------------------------
Debug Information


Operating system detected on registry: 7 - AMD64
True operating system (kernel.dll):    7 - AMD64
npptools.dll present on the system:    false
netnm.inf present on the system:       false

End of log
-----------------------------------------------------

I've run the Wireshark install "as Administrator" with the same results.

What shall I do?  I'm stuck.

Thanks,

Fred
