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:
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.
