Frequently Asked Questions

Why did my Microsoft Word app suddenly disappear from my computer?

This can happen if a recent Windows or Office update failed or was interrupted, corrupting the application files. An expired subscription can also prompt the system to restrict or hide access to the desktop executables.

Why does Excel force open in the browser instead of the desktop app?

Office automatically redirects to the browser if it detects an inactive license, if you are signed in with the wrong Microsoft account, or if your specific subscription tier only supports the web versions of Office applications.

Will running an Online Repair delete my saved Word or Excel files?

No. The Online Repair tool only modifies system files, program installations, and registry keys associated with the Office software. Your personal documents, spreadsheets, and files are completely safe and will remain untouched.
