Hi! 

Hopefully I found my way to the right forum now.... 

So I'm running Office Pro 2013 using a KMS, this worked great in Windows 8, but after the update to 8.1, it has stopped working...

I've understood that a way to solve this is to install and update the KMS host by the use of this file: KB28885698 

However when I'm trying to install it, it says that it is: "not applicable to my computer"....I have tried with versions: x64 windows 8 and x64 windows 8 server 2012...nothing works...

So how can I make my KMS work in Windows 8.1?

Cheers! 

Hi,

KB2885698, is only needed on down-level KMShosts which need to service Win8.1 or WS2012R2.

What is the OS of your KMShost, and what is the OS of your KMSclient ?

Have another look at that number. I think you have a typo there. Updates are only 7 digits. ( for m

Hi

I have my KMS host over Windows Server 2012 R2. However i Can't load keys for Windows 7 and Windows server 2008.

the error that displays is:

@Gary, this is expected.

You cannot, and do not need to, install Win7 nor WS2008 keys into a newer KMShost OS.

If your KMShost computer OS is WS2012R2, you must use the WS2012R2 KMShost product key, which will activate the KMShost OS itself, and also activate the KMShost features for serving all KMSclient OS versions/editions.

A KMShost, when running on WindowsServer OS, will issue activations for all KMSclients at the same OS version/edition and all lower version/editions.

You can only install ONE KMShost product key on a KMShost.

(note that Office KMShost function is a totally different story)

So, if your KMShost OS is WS2012R2, you need a WS2012R2 KMShost product key.

If you don't have a WS2012R2 KMShost product key, and if you aren't entitled for that, you must choose a different OS for your KMShost.
