I have already downloaded it and checked it, it is working fine without issue.

If you have installed Evaulation version and unable to use KMS key then Try mentioned link, it is very helpful

Steps are

1. check Current Edition

DISM /online /Get-CurrentEdition

2. Check Target Edition

DISM /online /Get-TargetEditions

3.

DISM /online /Set-Edition:ServerStandard /ProductKey:D2N9P-3P6X9-2R39C-7RTCD-MDVJX /AcceptEula

or

DISM /online /Set-Edition:ServerDatacenter /ProductKey:W3GGN-FT8W3-Y4M27-J84CP-Q3VJ9 /AcceptEula

Now you can install the new Windows 2012 R2 KMS key. If you run in to any issues here, restarting the KMS Service can help (("net stop sppsvc" and "net start sppsvc") . Try that first.

4.

slmgr.vbs /ipk D2N9P-3P6X9-2R39C-7RTCD-MDVJX

or

slmgr.vbs /ipk W3GGN-FT8W3-Y4M27-J84CP-Q3VJ9

once it done, we can cross check the time period

slmgr.vbs /dlv
