Running NAVW32 via Command Line

Hi,

I'm trying to run a file scan via the command line using the information provided here.

When I run any NAVW32 command though I get the following pop up:

"Before continuing, please read and accept out License Agreement. Do you want to view the License Agreement now?"

Clicking Yes or No closes the pop up but seems to do nothing, I get no further output from the application. How do I accept this license agreement?/What am I doing wrong?

What I'm running: "C:\Program Files (x86)\Norton Internet Security\Engine\21.7.0.11\navw32" /?

Version: 21.7.0.11
