Cannot login to activate Word/Excel 2016 - Activate form returns blank page.

After updating OSX to latest edition of  10.13.3 and iWork Apps I cannot login to my Microsoft account. Attempted login returns a blank page with nowhere to enter login credentials. Both Word 2016 and Excel 2016 return Get Started/Activate pages with no access to Activation fields.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Reset the SMC, then reset the PRAM.  See if that fixes it.

If not, reinstall Office.
If that doesn't work, then reinstall OS X.

Did you upgrade from 10.13.2 or from 10.12 or earlier?

I assume you mean Office Apps not iWork (which is the Apple software Numbers, Pages & Keynote)

Did you run the AutoUpdater to ensure Office apps are up to date before doing a re-install?
The updater is located in
/Library/Application Support/Microsoft/MAU2.0/Microsoft

>>> Did you upgrade from 10.13.2 or from 10.12 or earlier? - No
>>> Did you run the AutoUpdater... yes (no updates)

>>> assume you mean Office Apps not iWork... I did mean iWork, finishing migration to new Mac Mini required iWork updates.

ReInstalled Office 2016 for Mac - same problem

Checked  in here,,, Activate Office 2016 for Mac - Help

Above link returned (among many other items):

Note: If there is no What's New window, you may need to activate from within the Office app. On the top menu, click Word >Activate Office > Sign in.

>>> Word >Activate Office > Sign in,,,   no such link!!

Hopefully someone has other ideas...

Well now, after several days of frustration attempting to solve this 'Activate' requirement, suddenly I was able to activate Office.

Problem solved... How? Don't know, but now able to use Office 2016 components.

Thanks to all who made suggestions.

BTW, migrating MacOS High Sierra from one Mac mini to another is not very tolerant of non-Apple Apps.

It's not exactly Apple's fault.  Apple's Migration assistant does copy that license file correctly as an exact copy.  Microsoft created a hashed license file based on the system ID and just copying the file does not give you access, because you are now on a different system ID.  If you copied it back as a way to repair the computer, it would work.  Ever since Autodesk won against Vernor in the 9th Circuit Court District, a lot of companies are making licensing more difficult.  The top 3 troublesome licenses to deal with are Microsoft, Autodesk and Adobe.
