I initially installed Windows Server 2012 R2 Standard Evaluation from Microsoft's website because I didn't have the funds at the time to buy the license. When The trial period ended though, I went to Amazon and bought a copy. But, when I put that key in to activate I get an error "that key cannot be used to activate this version of windows". Now I am stuck I spent $600 and I don't know how to get this key to work.
Can anyone provide assistance or advice?
Thank you
