Frequently Asked Questions

Will running an Online Repair delete my Word documents?

No. Running an Online Repair for Office 2021 only resets and repairs the application files. It will not delete, move, or modify any of your saved personal documents.

Why does the Bad Image error also affect Excel and PowerPoint?

Although the error specifically mentions winword.exe, Office applications share core system files and Visual C++ libraries. If a shared component is corrupted, the error will trigger across all Office programs.

How do I test if a Windows background service is causing the winword.exe error?

You can perform a Clean Boot by typing 'msconfig' in the Windows search bar, hiding all Microsoft services under the Services tab, disabling the remaining startup items, and restarting your PC to test Word.

Can a corrupted Windows user profile cause the Bad Image error?

Yes. If system variables in your profile are damaged, Office apps may fail to launch. You can test this by creating a new local Windows account via Settings > Accounts > Other users and attempting to open Word there.
