Frequently Asked Questions

Why does the Microsoft Translator add-in say it isn't set up properly?

This error is typically caused by corrupted Microsoft Office installation files, a conflict with another third-party COM add-in, or background Windows programs interfering with the application's network or registry access.

How can I check if the issue is with my computer or the add-in itself?

A great troubleshooting step is to log into Microsoft Office for the web (like Word for the web) and try using Translator there. If it works online but not on your desktop application, the problem is isolated to your local software configuration.

Will running an Online Repair delete my Office documents?

No, running an Online Repair for Microsoft 365 or Office only uninstalls and cleanly reinstalls the application's core program files. Your personal documents, spreadsheets, and files remain completely safe and untouched.
