Installation files for Navision 2009 R


We have a client who have Navision installed on their network. We have supplied new laptops and need to install the Navision client onto these. However they have no installation media and the company that supported their Navision installation have ceased trading. I have hunted and cannot find anything to install with, and wonder if someone can point me to a location where I can source these from. They seem to be on a very old version - 2009 - with a version of 6.00.32012 and i assume that this is the installer that I would need.

Can anyone help us out with a link to some installation media for them. 

Many thanks
