Restart Windows and Install System Updates

Often, a simple system restart and ensuring your operating system is up to date can resolve unexpected software launch failures.

Temporary background processes or pending system updates can sometimes interfere with Microsoft software. Restarting clears out hung background tasks, while updating ensures your system has the latest compatibility patches.

1
Restart your computer

Click the Start button, select the Power icon, and click Restart. Wait for Windows to fully reboot before trying to open the software again.

2
Check for Windows updates

Press the Windows key + I to open Settings. Navigate to Update & Security (or Windows Update) and click 'Check for updates'. Install any available updates and restart your computer if prompted.

Frequently Asked Questions

Why won't my Microsoft Word open?

Word may fail to open due to conflicting add-ins, a stuck background process, or corrupted installation files. Try restarting your computer or launching Word in Safe Mode by holding the CTRL key while opening it to isolate the issue.

Will repairing Microsoft Office delete my files?

No. Running the built-in Office repair tool from Windows Settings only replaces or fixes corrupted program files. Your personal documents, spreadsheets, and presentations will remain completely untouched.

How do I know if my Microsoft software issue is system-wide?

Try opening a variety of different programs. If only Microsoft apps fail, it's likely an Office installation issue. If other non-Microsoft apps also fail to launch, your Windows operating system might need an update, or you may be experiencing hardware issues.

What should I do if the repair tool doesn't fix the issue?

If repairing does not work, you should completely uninstall and then reinstall the Microsoft software. Additionally, temporarily disable any third-party antivirus programs, as they sometimes falsely flag and block Office applications from launching.
