Unable to install windows server 2012 free evaluation edition.Having problem with product key and windows activation.Stuck with cmd.exe with no active network adaptor connectivity

Hi @Anis Butt

How did you get the Evaluation copy on firsthand? You cannot perform an in-place upgrade with the evaluation media you must get the Evaluation copy and clean install it.

Based on your error code I can see that your machine is trying to activate the version and is getting failed.

Make sure your machine has the hardware compatibility for the Evaluation copy you are going to run.

Hope this resolves your Query!!
