Observed behavior
An error dialogue stating "entry point not found" blocks the app from opening, and the issue persists even after basic system file checks or initial repair attempts.

Reset or Reinstall the Office App

Use the built-in Windows Settings to completely reset or reinstall the free Office app, which clears corrupted installation files that trigger the entry point error.

Open Windows Settings

Press the Windows key + I on your keyboard to open the Settings menu.

Navigate to Apps & Features

Click on "Apps" in the left sidebar, then select "Installed apps" or "Apps & features" depending on your Windows version.

Scroll down the list to find "Office" (or "Microsoft 365 (Office)"). Click the three-dot menu icon next to it and select "Advanced options".

4
Reset or Uninstall

Scroll down to the Reset section and click the "Reset" button. If the error continues after a reset, return to this menu, click "Uninstall", and download a fresh copy from the Microsoft Store.

Frequently Asked Questions

What does "Entry Point Not Found" mean in Windows?

This error usually means a software program is trying to access a specific file (often a DLL file) or system function that is missing, corrupted, or incompatible with the current version of Windows.

Will resetting the Office app delete my saved documents?

No, resetting or reinstalling the free Microsoft Office app will only clear the app's local cached data and settings. Your actual documents are saved safely on your hard drive or stored remotely in OneDrive.

Why does the free Office app open my browser instead of a desktop program?

The free Office app for Windows is primarily a centralized dashboard or launcher for Microsoft's web-based Office applications. If you do not have a paid Microsoft 365 desktop license installed, clicking a document in the app will automatically route you to the free web version in your default browser.

How do I repair the full Microsoft Office desktop suite instead of the free app?

If you have the full Office suite installed and it is producing errors, open Windows Settings > Apps > Installed apps. Scroll down to "Microsoft Office" or "Microsoft 365", click the three dots, select "Modify", and then choose either "Quick Repair" or "Online Repair".
