I have installed my copy of Win Server 2012 Essentials onto a server and the server is now too old and going too slow. It was old to start with. I have bought a new box and want to install this on the machine. I have entered the key when installing and the software is telling me that its not correct. It is correct but I can't install the software.  I want to know how to solve this issue.  The old server is to be wiped once the new one is built.
