SCCM Service Pack 1 Client Fails to Install - Error 0x800b0101

I recently encountered a failure in installing an agent when I had already upgraded my SCCM 2012 server with Service Pack 1. I had no problems installing agents before this. Looking at the CCMSETUP.LOG file using the Trace utility, I noticed this line being highlighted:

Couldn't verify 'C:\WINDOWS\ccmsetup\MicrosoftPolicyPlatformSetup.msi' authenticode signature. Return code 0x800b0101

Searching on the net, I found that this was a known issue and a patch available at

After applying the patch, the SCCM Agent deployment was successful.
