How do we get a potential customer to let us visit him to show a demo of our vertical app. without mentioning that our solution is computer based?

We realized that some of the contacts we established did'nt really go well because of the computer factor. In some cases we still got to show a demo and those that seemed to be anti-computer reacted very well.

So the best thing for us would be to show them a demo of our solution without ever mentioning computers. Why take chances and mention it if it could get a potential customer in a bad mood.

So is there a way to approach them considering those possible fears of computers?

Is what we're looking for the best solution or would it be better to mention that our solution is computer-based but give them a bunch of reasons why they really must see our demo?

If you think that we should mention the computer-based solution what do you think would be the best overall way to approach them?
