This guide will walk you through easy solutions, starting from basic checks to more advanced troubleshooting. Each step is explained clearly to help even beginners resolve the issue.

By following these instructions, you can get your Office applications working smoothly again without needing technical expertise.

Let’s start with some quick notes before diving into the solutions.

Quick Note

• Make sure your Windows 11 is up to date. Sometimes, system updates fix compatibility issues.
• Check if your Office 2013 or 2016 installation is genuine and activated.
• Close all Office programs before starting any repair process.
• Have a stable internet connection, as some fixes require downloading files or updates.

Step 1: Restart Your Computer

Before doing anything complex, try restarting your computer. This simple action can clear temporary glitches causing the red X error.

Restarting ensures all updates and background processes are refreshed, which can resolve minor conflicts affecting Office apps.

Step 2: Run Office Repair from Settings

Windows 11 offers a built-in repair tool for installed programs like Office. This tool can fix corrupted files or settings causing errors.

Follow these steps:

1. Click the Start button and select Settings.
2. Go to Apps, then click Installed apps.
3. Find Microsoft Office 2013 or Microsoft Office 2016 in the list.
4. Click the three dots next to it and choose Modify.
5. Select Quick Repair first, then click Repair.
6. Wait for the process to complete, then restart your computer.

If the error persists, repeat the steps but select Online Repair this time. This option is more thorough but requires an internet connection.

Step 3: Check and Update Office

Outdated Office versions can sometimes cause errors due to compatibility issues. Updating Office ensures you have the latest fixes.

Here is how to update Office:

1. Open any Office app (like Word or Excel).
2. Click File in the top-left corner.
3. Select Account or Office Account from the menu.
4. Under Product Information, click Update Options.
5. Choose Update Now.
6. Wait until updates install, then restart your computer.

Step 4: Delete Office Cache Files

Note: If you use Office 2013, replace 16.0 with 15.0 in the path above.

Office programs need proper permissions to access files and system resources. Incorrect permissions can cause red X errors.

To check and fix permissions:

1. Navigate to C:Program FilesMicrosoft Office or C:Program Files (x86)Microsoft Office.
2. Right-click the Office folder and select Properties.
3. Go to the Security tab.
4. Ensure your user account has Full Control or at least Read & execute permissions.
5. If not, click Edit, select your account, and check the appropriate boxes.
6. Apply changes and restart your PC.

Alternative Method: Reinstall Office

If none of the above solutions work, reinstalling Office might be necessary. This process replaces corrupted files with fresh copies.

To reinstall Office:

1. Open Settings > Apps > Installed apps.
2. Find your Office version, click the three dots, and select Uninstall.
3. Follow the on-screen prompts to complete uninstallation.
4. Restart your computer.
