When installing WinPcap 4.1.2 (as well as earlier versions) I get the following error:

An error occurred while loading the WinPcap Install Helper DLL

I checked the WinPcap FAQ but there was nothing relevant.

Is there a way around this?

The problem occurs if you've installed update KB2264107.

You need to modify your registry to add a CWDIllegalInDllSearch entry for the WinPcap installer.

Create a .reg file with the following contents:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\WinPcap_4_1_2.exe]
"CWDIllegalInDllSearch"=dword:00000000

And merge it (make sure the name/version number of the .exe matches the name of the WinPcap installer). Now re-run the install and everything is hunky-dory.
