Error messages when running Microsoft Autoupdate

To stop the error messages related to updates for Microsoft Office 2013 versions of Error Reporting and Silverlight, you can try the following steps:

1. Disable Automatic Updates: If you do not need updates for older versions of Office, you can disable automatic updates for Microsoft Office. This can often be done through the Microsoft AutoUpdate application. Open Microsoft AutoUpdate, go to Preferences, and set the update frequency to "Manually".
2. Check for Installed Applications: Ensure that there are no remnants of the older Office versions on your Mac. Sometimes, leftover files can trigger update prompts. You can check your Applications folder and remove any old Office applications that you no longer use.
3. Use the Microsoft Support and Recovery Assistant: This tool can help diagnose and fix issues with Office installations. It may help resolve the error messages you are encountering.
4. Group Policy Settings: If your Office installation is managed through Group Policy, you may need to contact your IT administrator to adjust the settings that are causing these messages.

If the issue persists, consider reaching out to Microsoft Support for further assistance specific to your situation.

Hi,

The weekly AutoUpdate errors happen because leftover update receipts from older Office versions (2011/2013) were transferred to your new Mac during migration. AutoUpdate still thinks those components Error Reporting and Silverlight exist, so it keeps trying to update them and fails.

To stop the prompts:

Delete old update receipts from /Library/Application Support/Microsoft/MAU2.0.

Reset Microsoft AutoUpdate preferences.

Remove any remaining legacy Office files from your system.

Once those remnants are gone, AutoUpdate will only check for your current Microsoft 365 apps and the messages will disappear.

Happy to help!

Annoying, yes, but harmless. They are remnants from earlier editions of Mac Office which MAU simply cannot update because there are no updat4es for them. When you run MAU click the ⓘ adjacent to each listing & select the Show in Finder command or use the macOS search features to locate them & safely delete them.
