If the CACE installer isn't working, or Microsoft-supplied tools don't 
help locate the driver, maybe OSR's DriverTree might help find it.

Process Explorer and Process Hacker also might help show the process 
that is using it. If not obvious there, try an IRP-based tool, like 
Process Monitor or IRP Tracker or FileSpy, to search for who is opening 
the WinPCap device.

Unlocatable strangely-installed sofware sounds to me like malware. If 
you don't know what is on your box, reformat and reinstall Windows, and 
pay attention next time. :-)

Please speak up if/when you find the software that is installing this 
driver in a nonstandard way. Someone asked a similar question a few 
months ago.
