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

    I spent a day trying to understand why all of a sudden packages were no longer installing via OSD. Has anyone seen anything official from MS on this?

    Follow-up to my previous comment:

    If you apply KB2749655 as a workaround, you will be able to deploy your image successfully.
