I have a Windows 7 box that is a KMS server for Office as well as Windows 7. I now want to do KMS licensing for Server 2012 R2 Datacenter version. I have followed documents that I have found from MS to install a need update - 2757817. However, when I attempt to activate a legitimate KMS key for server 2012 I get an invalid license message with error code 0xC004F050... which is the error code that I trying to avoid by applying the update.
What can I do?
