10.1.3 downloaded fine.
I deleted 10.1.1 and 10.1.2a from ZCC.
I deployed 10.1.3 to the server.
I go to the server object and click on Refresh Server, when I go back to Configuration => System Updates, the deployment failed.

So, I downloaded the manual installer. I went through that process and it's still failing after I click Refresh Server.

I'm currently at 10.1 on Win2k8 (64bit) Standard.
