Office 12.2.1 update failing

Hi everyone, has anyone gotten the 12.2.1 update to run properly in instaDMG? We have an enterprise copy of Office, so it's not serialized. So I put it in the image. I have an installer for 12.2.0. When I put 12.2.1 to install, it does not run. I'm left with 12.2.0 still. The .pkg log shows: "Installing Quit Microsoft Applications" So I take that this is a metapackage, that runs a sub routine that first quits any open MS applications. The problem is, it's not running the other routines. Anyone gotten around this yet? Thanks!
