Run the Office Repair Tool via Programs and Features

Press the Windows key + R on your keyboard, type 'appwiz.cpl' into the Run dialog box, and press Enter.

Frequently Asked Questions
Why doesn't Microsoft Office 2019 show up in my account?
Office 2019 will only appear under 'Services & subscriptions' if it was properly linked to that specific Microsoft account during the initial setup. Ensure you are signing in with the exact email address used when you first purchased or activated the product key.
What is the difference between Quick Repair and Online Repair?
Quick Repair runs locally on your computer and fixes most basic application issues quickly without needing an internet connection. Online Repair takes longer and requires the internet, as it uninstalls the corrupted components and downloads fresh copies of the Office files directly from Microsoft.
Can I get a refund if my Office Home & Student 2019 stops working completely?
Refund eligibility depends on how recently you purchased the software, the original seller's return policy, and your proof of payment. If purchased directly from Microsoft, you can check your eligibility or request assistance through the Microsoft Support and billing portals.
