Modify the Installation

Click on the Microsoft Office 2019 entry and select the 'Modify' button. If prompted by User Account Control (UAC) asking if you want to allow the app to make changes, click 'Yes'.

4
Execute Quick Repair

In the repair window that appears, select 'Quick Repair' and click the 'Repair' button. Wait for the process to complete, then try opening Word or Excel again.

Frequently Asked Questions

Will repairing Office 2019 delete my personal files or settings?

No, running a Quick Repair or Online Repair only fixes the application files, registry entries, and shortcuts. Your personal documents, emails, macros, and custom settings will remain intact.

What should I do if the Quick Repair doesn't solve the issue?

If Quick Repair fails, you can return to the 'Modify' menu in Apps and Features and select 'Online Repair'. This takes longer and requires an internet connection, as it performs a comprehensive fix by downloading a fresh copy of the Office installation files.

Why do Word and Excel suddenly stop working when they were fine yesterday?

Sudden failures can occur due to conflicting third-party add-ins, corrupted temporary files, a recent problematic Windows system update, or overly aggressive antivirus software blocking the Office application processes.

Can I open Office 2019 files if the application itself won't launch?

Yes. If the application is broken, the files themselves are usually safe. You can open them using an alternative suite like WPS Office, or by uploading them to a cloud service like Microsoft OneDrive or Google Drive.
