It is set to install updates automatically.

2472264 
These are Microsoft patches
Whenever I try to install them I receive an error
Googling the error, I have tried extracting the file and using CMD prompt to install the xml file to install but to no avail.
I have installed Windows Identity Foundation as a role. It is necessary for this to be 
I have also noticed that all updates for a couple of weeks have failed. I have 2 other servers in the farm, both of which are joined to the same private network cannot look for updates with another error. Not sure if these are related.
Anyone know of anything like this?

Answer 1

right-click the file and select properties.
On "Digital Signatures" the tab, select the "Microsoft Corporation" entry and click "Details"
In the "Digital Signature Details" dialog, click "View Certificate"
In the  "Certificate" dialog, click "Install Certificate..."
In the "Certificate Import Wizard" dialog, select "Local Machine" (though current user might work, didn't use it, so I can not attest to it) and click "Next"
Select the "Place all certificates in the following store" option and click "Browse"
In the "Select Certificate Store" dialog, select "Trusted Publishers" and click "Ok"
Back in the "Certificate Import Wizard" click "Next"
You should now be at the "Completing the Certificate Import Wizard" step of the "Certificate Import Wizard" ... click "Finish"
You should get "Import was successful"
You should now be able to install the package.
