Client Agent Certificate Problem – Hotfix KB2801987

Attention: Downloads of SCCM 2012 SP1 done after 29. of January 2013 do not need this hotfix, it is already included in the source!

The Hotfix KB2801987 is available ( and solves the problem with the client installation on SCCM 2012 SP1 – see article  here!


SCCM 2012 SP1: Agent install problem starting 11th of January 2013

Starting today, it’s not possible to install the SCCM 2012 SP1 Agent! So it’s also not possible anymore to deploy an Operating System!

The problem is the MSI named “MicrosoftPolicyPlatformSetup.msi” in the %InstallDir%\Client\x64 or x86! The file is signed with a certificate, which was valid until yesterday, 10th of January 2013! And the Agent installation checks this certificate…

The error is: Couldn’t verify ‘C:\Windows\ccmsetup\MicrosoftPolicyPlatformSetup.msi’ authenticode signature. Return code 0x800b0101 ccmsetup

SCCM 2012 without SP1 (Cum Upd 1): The certificate will be available until the 1st of February 2013.

We will blog and twitter when the MS Patch is available…

Kind regards

SCCM 2012 SP1–Upgrade Silverlight on the clients to still use the WebShop

Do you use the SoftwareShop (WebBased) integrated in SCCM 2012 RTM? If yes, take a look here before upgrading to SCCM 2012 SP1…

The Softwareshop in SCCM 2012 SP1 needs Silverlight 5.1.x to connect! If you have installed an older Version on the clients, they cannot connect anymore to the shop after an upgrade to SCCM 2012 SP1! The easiest way to solve it: Deploy the new sccm agent to the clients, this will install all prerequisites automatically – including Silverlight 5.1.10411.0!

You have several possibilities to deploy the agent: My favorite is by “Automatically Upgrade the Configuration Manager Client for the Hierarchy” or “How to Upgrade Configuration Manager Clients by Using a Package and Program”.

That’s it!
