Installing SQL Server 2016 on Windows Server 2012 R2: Rule KB2919355 failed

If you are trying to install SQL Server 2016 on Windows Server 2012 R2, under certain circumstances, you might get the below error message:

Rule "KB2919355 Installation" failed.

KB2919355 Check Failed. If you have installed KB2919355, please make sure you have restarted your machine. For more information, you can visit

The first logical thing to try is of course to install the reported set of patches under the name "KB2919355".

However, when you try to install KB2919355 you might get an error message as well, just like the below:

"This update is not applicable for you computer"

So, what do you do?

A possible reason for not being able to install KB2919355 is that it is missing another prerequisite patch: KB2919442

I know, all this prerequisites thing can be a little bit annoying sometimes but what else can we do? :)

So, in order to overcome the issue and be able to install SQL Server 2016 on your Windows Server 2012 R2, you can try first the below set of actions:

Step 1: Install patch KB2919442

Step 2: Install patch KB2919355. Note that KB2919355 is not a single patch but a package of KBs which, as provided in Microsoft's instructions, need to be installed in the following order:
- clearcompressionflag.exe
- KB2919355
- KB2932046
- KB2959977
- KB2937592
- KB2938439
- KB2934018

Note about Step 2: Almost each one of the patches will require to reboot the computer after installation. Prior to each reboot, first make sure that you don't have any applications open or any unsaved work.

Step 3: Try again to install SQL Server

Hope this helps!
