Frequently Asked Questions

Why do my Office apps display an error and close immediately?

This issue is typically caused by corrupted Office installation files, conflicting background services, or a damaged Windows user profile. Running the built-in Office repair tool is the best first step to resolve it.

Will repairing Microsoft Office delete my personal files?

No, running the Office Repair tool or the Microsoft Support and Recovery Assistant only affects the application files and registry settings. Your personal documents, spreadsheets, and emails will remain untouched.

What should I do if the clean boot fixes the crashing issue?

If your applications work correctly during a clean boot, it indicates a third-party service or startup program is causing the crashes. You should re-enable your startup services one by one to identify and permanently disable the specific software causing the conflict.

How do I completely reinstall Office if the repair fails?

If a standard repair does not work, download the Microsoft Support and Recovery Assistant from the official Microsoft website. This tool will completely remove all traces of your current Office installation so you can perform a clean reinstall from your Microsoft account.
