Install SQL Server 2012 .iso On a Server Via RDP

Ok this actaully drove me nuts for quite a few days everything i tried just did not work. in the end i copied the .iso to the web server and then extracted the contents of the file to a folder using 7-zip. Then i just ran the setup.exe - fortunately this appeared to do the trick.

I do hope this is useful for someone else and they learn from our pain.
