Error when update?

Hi @Brown Jack,

I'd like to learn a bit more about the issue so I can better understand what's happening and help you troubleshoot it effectively.

I noticed that your question was posted under the For Education category. Could you please confirm whether you're using a Microsoft 365 work/school account provided by your school/organization, or a personal Microsoft account?

Additionally, could you share the following information:

• What is the exact error message you receive when updating or opening the app? A screenshot with any personal information removed would be very helpful.
• Which version of macOS are you currently using?
• Does the issue only affect Word, or are other Microsoft 365 apps (such as Excel, PowerPoint, or Outlook) experiencing the same problem?
• Are you able to sign in to and use Word for the web successfully?

In the meantime, please try the following:

• Fully restart your Mac, then try opening Word again.
• Make sure macOS is updated to the latest available version (Apple menu > System Settings > General > Software Update).
• If Office was downloaded directly from Microsoft, run Microsoft AutoUpdate and install any available Office updates.

Please try the steps above and let me know the results. Also, feel free to answer the questions above, as they will help me narrow down the cause of the issue and determine the most appropriate next steps.

I look forward to your reply.
