"Class not registered" error

Can you use Windows logo key shortcuts here to get to what you need to repair it?

If not I'd install Media Creation Tool on another PC to create bootable media or download the ISO file, transfer it to problem PC, open the media or click to mount the ISO file (using Windows key + E to open Explorer if needed), right click to run Setup as
Admin. This will do a Repair Install.

If you can't reach the media then open a CMD or Run box using the shortcuts or from Advanced Startup Options Command Prompt reached using one of the methods here:

"Class not registered" error

Open Start > Settings > Apps > Apps & features

Scroll down to Microsoft Office

Select it

Click Change

Now, wait while the repair wizard starts up.

Choose the type of repair you would like to perform. Depending on the severity or availability of your Internet connection, you could try the first option, Quick Repair, which is much faster and tries to fix the problem without a data connection.

If that doesn’t resolve the problem, then go back and try the Online Repair option. For my particular issue, I ultimately had to use the Online Repair.

The repair process is straight-forward following the wizard. Note that you’ll need to save your work and close all Office programs first, and then click Repair.

Then wait while the repair process runs.

You will notice the repair experience is similar to a fresh installation. The amount of time it takes will depend on your connection speed and what the issue is.

You will see your Office apps light up in their respective colors while the repair completes.

Once the installation is complete, restart your computer just to be sure and launch your apps and verify if the problem you were having is resolved.
