A family of Microsoft word processing software products for creating web, email, and print documents.
We see many reports in the forum that Repair Now does not work.
Instead, restart your computer and then run an Online Repair of Office. See https://support.microsoft.com/en-us/office/lifecycle/repair-an-office-application .
Note that an Online Repair includes a reinstall of Office, as the last step. Therefore, before you begin, you should verify that you can access your account at https://account.microsoft.com/services and that Office is associated with it.
