Hi
I recently re-installed Windows 10 (first anniversary edition, then updated to Creators Update afterwards) and now I get the dreaded "Sorry, we ran into a problem while trying to install the product key. If this keeps happening, you should try repairing
your office product. System Error 0x80070005)" pop-up when trying to active office.

I've tried:
- Quick repair
- Online repair
- Running Office (Word - but same issue for all applications) as administrator to see if that helps
- Uninstall and re-install
- The easy fix tool (https://support.office.com/en-us/article/Uninstall-Office-2016-Office-2013-or-Office-365-from-a-PC-9dd49b83-264a-477a-8fcc-2fdf5dbf61d8?ui=en-US&rs=en-US&ad=US&fromAR=1)
to completely remove Office and then re-installing again.
- cscript OSPP.VBS /act (I saw this mentioned here: https://answers.microsoft.com/en-us/msoffice/forum/msoffice_install-mso_win10/issue-with-office-2016-on-windows-10/3543215c-036a-4f95-89e2-2d77960b14bd)
This was initially for Office 2016 Professional under the HUP. Thinking perhaps it didn't like the license key after the re-install, I also signed up for an Office 365 Home subscription to see if that worked. I uninstalled Office 2016 and installed Office
365 Home - and I hit the exact same issue. Obviously I've cancelled the subscription - it's still valid for a couple of weeks but will not renew.

It also shows this pop-up.
I would really prefer not to spend hours on the phone for this - and also prefer not to reinstall Windows given that I did that very recently.
[Note: This is regular Windows 10 Creators Update installed, not an insider preview or anything like that. ]
