Hello,
There will be no compatibility problem with the NEFF470 if the PC is replaced.
Is there a specific reason why you are installing NI-488.2 ver 1.6?
Ver 1.7 is our latest software for NT. Are you installing the software before the hardware? When exactly do you get the message displayed in the Error #1 screenshot? Is it after you boot up for the first time after inserting the card? Don't worry about the interface not being verified, there are a number of reasons why that could be happening, none of which affect the functionality of the card.
