A family of Microsoft word processing software products for creating web, email, and print documents.
Try these steps in order:
- Restart the PC, then try opening Word again.
- This can clear an Office update or repair process that is stuck.
- Run an Office repair from Windows, not from the Word error popup.
- In Windows 10: right-click Start > Apps and Features.
- In Windows 11: right-click Start > Installed apps.
- Select Microsoft 365 or Office > Modify.
- Choose Quick Repair first.
- If Word still does not open, run Online Repair.
- Note: Online Repair is more complete, but it requires an internet connection and may effectively reinstall Office.
- If Word starts showing a “stopped working” type error, check add-ins.
- If Word can open at all, disable add-ins one by one and test again.
- Older versions of ABBYY FineReader and Dragon Naturally Speaking are specifically called out as known causes with Office 2016.
- Install Windows updates.
- Go to Settings > Windows Update > Check for updates.
- Install available updates, then restart the PC.
- This can fix problems caused by incompatible older device drivers.
- If the error says Office is busy or unable to start because Office is updating, adding, or removing programs:
- Wait a few minutes and try again.
- Restart the PC.
- If it still continues, uninstall and reinstall Office using the Microsoft troubleshooter.
If the main goal is to open important Word files urgently, and the problem is with a specific document rather than Word itself, try opening the file with File > Open > Browse, select the file, then use the arrow next to Open and choose Open and Repair.
