Can't start Office apps or open Office files after upgrading to Windows 10

If you recently upgraded to Windows 10, you may see errors when you try to start an Office 2013 app or open an Office 2013 file or email attachment.

  • For example, you may see a message that the Office app has "run into an error that is preventing it from working correctly" or that the "file is corrupt and cannot be opened."

  • If you can start an Office 2013 app but can't open a file, start one of your Office 2013 applications, such as Word, and then click File > Account > Update Options > Update Now. For more information, see this article.
