KB4103726 Windows Server 2012 R2 x64

Occasional Visitor

Good Morning,


I am trying to install KB in subject for Windows 2012 R2 Standard.

I have downloaded it from Microsoft Update Catalog as stated in KB article.

I can't install the KB as "The update is not applicable to your computer".


I noticed that the folder containing the file is named:

2018-05 Security Only Quality Update for Windows Server 2012 for x64-based Systems (KB4103726)

While the file inside is named:


I also noticed that if you download the file for Windows 8 x64, the file has the same name.


Can someone confirm this is the right file for Windows Server 2012 or there is a problem in the Catalog?


Thanks in advance.
