Is there a trial version of this software?
No, there is no trial version for this application. I've visited the official website and it appears the software is on a commercial licence. This means you will have to pay first and the software will be delivered to you after the payment is complete. It's a usual rule encountered for many applications nowadays.
The software will cost you 399.00 $ and it can be purchased using the following link: http://www.mountaincow.com/shop.SW.IA.html
However, get in touch with the developers and ask them for a trial possibility: http://www.mountain-cow.com/mountaincow/Support.aspx
