Excel update download error in MAU

If you're encountering a "Download Error" when trying to update Excel through Microsoft AutoUpdate (MAU), there are a few steps you can take to troubleshoot the issue:

1. Check Internet Connection: Ensure that your internet connection is stable and that there are no network issues that could be affecting the download.
2. Disable Hardware Acceleration: Sometimes, disabling hardware acceleration can resolve issues with applications not functioning properly. You can do this by going to Excel's Options, selecting Advanced, and checking the box for "Disable hardware graphics acceleration".
3. Verify Updates: Make sure that your version of MAU is up to date. You can check for updates manually to ensure you have the latest version.
4. Check for Server Issues: If the problem persists, it might be worth checking online forums or Microsoft's support channels to see if there are any known server-side issues affecting downloads.
5. Use Manual Update: As a workaround, you can manually download the update packages from the Microsoft website and install them directly.

If these steps do not resolve the issue, it may be beneficial to contact Microsoft Support for further assistance.

Hello, good day and thanks for your question. May I check and confirm if it is happening on a specific channel on MAU as this was tagged under Microsoft 365 insider?

I checked the update today and the updates for Outlook and Copilot updated successfully. I then tried Excel again and it worked. It was a new version, so the last one must have had issues.
