On a Windows 8 x64 VM that was fully updated I've installed and registered Office 2013 Plus from the TechNet ISO DVD image.
The ISO image has
Release Date: 10/25/2012, and I choose manual updates just as I did in Windows 8 (I'm on the road often, I don't want automatic updates to kick in while on a slow or costly internet connection).
After installation, I did a reboot, then had the system check for manual updates through the control panel: none were available.
Since it is not a click-to-run install, the manual Office 2013 click-to-run update mechanism mentioned here does not work.
Also there is no "File -> Account -> Update Options" (I tried Word, Excel, Access and PowerPoint)
How can I force the update to happen?
