Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I finally have an answer that works on my Office 2013 Pro Plus (HUP) running on Windows 7 Pre 64-bit SP1, it involves downloading/running the Microsoft System Update Readiness Tool (for Win 7, Vista, Server in my case) from the Microsoft KB947821. It runs a Hotfix for Windows that takes some time to run, then it re-installed my Office 2013 without prompting (or possibly timing out on a request to fix Office, I was watching TV). I ran this when the MS Help suggested it while examining a failed Security Update, Control Panel -> Programs -> Programs and Features -> Installed Updates, to see if something was amiss that may be related to MS Office being inoperable after the June 2014 Security Updates.

I had already tried, rebooting and trying to run MS Office in-between, the following without success:
- Quick Repair under Control Panel -> Programs -> Programs and Features -> Change - > Repair.
- Online Repair under Control Panel -> Programs -> Programs and Features -> Change - > Repair.
- Uninstall KB2965788 (red-herring someone suggested was the source of the problem).
- Restored my system to a point in time prior to the June 2014 Security Updates.
- Running Windows Update again, installing all of the non-Optional updates.
Since it seems to be hit and miss depending on the Windows version and Office type this may or may not work.
