NDIS filter driver installation failed on Windows 7

NDIS filter driver installation failed on Windows 7

I am trying to compile the a WDK8.0 example: NDIS 6.0 Filter Driver. I got
ndislwf.sys and netlwf.inf built, but cannot install it. It said: "(Unable
to find any drivers for this device)".
My installation is like this:
Local Area Connection -> Properties
Click "Install..", select "Protocol", click "Add..."
Go to the folder that contains the two files.
Then windows gave me that alert. But I didn't change any source code of
ndislwf. I am running a Windows 7 Ultimate x86 system. What is the right
way to install ndislwf?
