Add a section to the installer, which sets following key to "1" on WIN NT, if the key is available. 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NPF\Start

With this key set to 1, the NPF service is started automatically at startup and then even users with restricted privilegies should be able to access Network Devices for capturing.
