To run NV1 Import:

I suggest that you backup your NV2 folder to a USB key and download the latest NV2 version and install it on your system which will recreate the the NV2 utilities on your Windows system.
The above command line switches assune you have installed NV2 in a folder called 2.08.18 on the root of the C drive.
