A family of Microsoft word processing software products for creating web, email, and print documents.
If you are seeing an option to Repair Now, you may already know that it often fails to work.
Instead, exit all of your Office apps and run an Online Repair; see https://support.microsoft.com/en-us/office/lifecycle/repair-an-office-application .
Before you begin, make sure that you can access your account at https://account.microsoft.com/services and that Office is associated with it, so that you can reinstall (which is usually the final step of an Online Repair).
