Prerequisite not satisfied: Before you install Skype for Business Server 2015, you must install an update for Windows Server 2012 R2.

When rolling out a Skype for Business 2015 Front End, I ran into the following issue after running the Deployment Wizard Step 2;

Skype for Business Deployment Wizard Error

Prerequisite not satisfied: Before you install Skype for Business Server 2015, you must install an update for Windows Server 2012 R2.  For details about the update, see Microsoft Knowledge Base article 2982006, “IIS crashes occasionally when a request is sent to a default document in Windows 8.1 or Windows Server 2012 R2” at http://go.microsoft.com/fwlink/?LinkId=519376.

At closer investigation of the Deployment Wizard I could see that KB2982006 is missing from the Windows 2012 R2 OS

The operating system was completely up to date with all latest Microsoft Updates, so in this case I used my trusted steed “PowerShell” to check if all the required windows updates where applied for KB2982006


Get-Hotfix KB2919442,KB2919355,KB2982006

This PowerShell command checks for the required KBs as well as the missing KB2982006

The resolution for installing KB2982006 is a simple one but you are required to use Deployment Image Servicing and Management otherwise known as DISM to install the KB

Resolution Steps

Download the KB to a location on your Server, for this Ill be using a temporary folder on the C: Drive called Patch. PLEASE NOTE: The folder must exist before running the below command.

Launch the Windows PowerShell console.

Type the following command;
expand -F:* C:\Patch\Windows8.1-KB2982006-x64.msu C:\Patch\KB2982006

Now type the following command;
dism.exe /Online /Add-Package /PackagePath:C:\Patch\KB2982006\Windows8.1-KB2982006-x64.cab

If you rerun Get-Hotfix KB2919442,KB2919355,KB2982006 you should now see the KB2982006 hotfix installed.

You will now be able to successfully complete Step 2 of the Deployment Wizard and build your Skype for Business Front End.
