Updating office and getting an error message (Office for Windows)

All of my Microsoft office product will not open 

I have windows 10 it's updated 

I have Office 2016 professional +  nothing works

I've done the following 2 times now and the programs work for a day than they stop again see below

Open Control Panel - Programs and Features

Click Microsoft Office in the list of installed applications

At the top, click 'Change'

On the resulting dialog, click 'Repair' - choose the Online Repair, it is a comprehensive fix

It there a fix so I wound have to do this everyday?

Thanks

Yes, the problem keeps returning again and again.

It seems the problem emerged after they rebranded it from Office 365 to Microsoft 365.

The rebranding was just that: a new name. It won't affect how Office programs work.

Which specific type of subscription license are you running? Home user license such as Microsoft 365 Family? Or a business license?

Since something is broken, you may have to remove all traces of Microsoft Office applications, for example by using the Uninstall support tool (see Option 2 in the article at https://support.microsoft.com/en-us/office/uninstall-office-from-a-pc-9dd49b83-264a-477a-8fcc-2fdf5dbf61d8). Make sure that Windows is up to date. Then reinstall Office. Of course, if you are running a business version, your organization may not allow you to do this yourself.

Check if there is a trial version installed on the computer, alongside your full version. In that case, the trial could be responsible for the message. You can uninstall the trial. 

Also, check with your school/college/university if something has changed with the licensing.

The Repair feature fixed it immediately.  And NOW it wants a product key.  I have 5 days to enter it. MS office 365 was already installed on this computer when I bought it so I have NO IDEA where the product key is.  Arrrgggghhhh.  I don't suppose there is a way to retrieve it out of the system files? 

Preinstalled versions of Office are usually trial versions. Unless the retailer explicitly said that you purchased a full version, a trial version is what you have. 

The issue with that for me is simple. As a student I received a fully registered, working version of Microsoft Office. Everything was peachy up until yesterday for me. Windows tried to update Microsoft Office Professional Plus 2016 but it it gave me the WINWORD.EXE error.

So that's ****. What do I do after that? I follow Dave's post up top.

"Hi Cindy

This seems to be a recurring problem this week for many users, follow these steps to perform a full repair of your Office installation . . .

Open Control Panel - Programs and Features

Click Microsoft Office in the list of installed applications

At the top, click 'Change'

On the resulting dialog, click 'Repair' - choose the Online Repair, it is a comprehensive fix

That should fix any issues with your Office Installation . . ." - DaveM121

I follow all the steps. Seems like things are going alright, although one of my disks are being gangf***ed by Microsoft's installation wizards. At 100% capacity. Yikes. (The screams of my C Drive still haunt me. They should really take some priorities to fix that.)

After that I make it to this window.

This is where a multibillion-dollar corporation lies through their teeth at its userbase. Nice. I'm starting to see why Anonimous5 became so annoyed; I wasn't "all set". Not in the slightest. Because when I open up Office again AND sign in with my Microsoft account, I get......This. My mind is blown. They told me that if I signed in I'd get full access! I had Office and then I didn't. I'm no computer genius, but how hard would it have been to transfer the license of the old version to the new one? Surely people here would get the gist of what I'm saying. So now I have to PAY MONEY for something that Microsoft decided was A-OKAY beforehand.

I refuse to throttle my drives getting this monster reinstalled. This is where I ask for some sort of assistance getting the full version back. Stefan, I know you don't work at Microsoft so I am not upset at you at all. You are doing what you can to help. Do you know of any way I can get the license key for my student version of Microsoft Office so that I don't have to pay for something that was already mine to start with? 

This Office nonsense comes across as thievery to me.
