SCCM 2012 SP1 - Client Push Fails with Authenticode Signature error

[Gatt]

Just found this issues when trying to install a new Win7 x64 client:

 

CCMSetup fails and the log shows:

 

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

 

Did a bit of a search and this seems to be a problem since SP1 was released:

Client push fails with Authenticode Signature error - Configuration Manager 2012 - www.windows-noob.com

 

There appear to be some hotfixes that work - but not yet sure how to get it working via OSD (OSD Worked but no SCCM Client was installed)

Just found an SCCM 2012 hotfix as well: Installation error 0x800b0101: System Center 2012 Configuration Manager Service Pack 1 client

Will need to try it later though...
