I know there has been lots of discussion already on installing WinPcap on Windows 8. I'm running the RTM version. I was able to install WinPcap without a hitch by using the Windows 7 compatibility mode.

Since then, I've noticed that WinPcap has stopped running and is actually no longer even installed. I tried installing it again, but now it continues to tell me that WinPcap does not work with my version of Windows. Compatibility modes and admin privileges make no difference. The only thing I remember doing to my system was installed >900MBs of Windows Updates.

Does anyone have any ideas about what I might do to get WinPcap installed?

I've already ensured that the compatibility mode settings I changed were in effect for all users.

I've already ensured that "run this program as an administrator" is checked on the compatibility tab for all users.

I've also tried installing WinPcap 4.1.2 and 4.1.1. No success with either.
