Unable to Deploy a Patch

I've scaned my systems, and it has displayed all available patches, and missing patches, etc, etc

So I tried to try a deployment on a patch that didn't need a reboot, so I could see it if worked, but going through all the steps to the point where it trys to deploy, and I end up with "Error Occured". The Error mirror message refers to

Error Occured: After a configuration is deployed, if there is any error in the Process like GPO linking failure,Download Failed,the Status of the Configuration will become "Error Occured".

This doesn't really help me, is there a way, or particular log file within the generated log file, or something that can tell me why it failed?

Regards
