A family of Microsoft word processing software products for creating web, email, and print documents.
If you are being offered an option called Repair Now, refuse it and do the following instead: Exit all Office apps and then run an Online Repair from Windows Settings.
Before you begin, verify that you can access your account at https://account.microsoft.com/services and that your Office product is associated with it. That way, you make sure that you can reinstall Office, which is usually the final step of an Online Repair.
Instructions for running an Online Repair can be found in the support article at https://support.microsoft.com/en-us/office/lifecycle/repair-an-office-application .
