Office documents may error when opened after a Windows 10 upgrade


If you have upgraded from Windows 7 to Windows 10, you may find that some of your Office 2013 documents result in errors when you try to open them in protected view using a Click-to-Run install of Office.  Protected View can occur when opening files from locations that may pose a threat such as Outlook or the internet.

Errors:

  • Excel:   "This file is corrupt and cannot be opened"
  • Word:   "Word experienced an error trying to open the file"
  • PowerPoint:  "Sorry, PowerPoint can't read <file name>"

This issue is being investigated. The KB article below includes steps to resolve the issue:

Important Notes:

You may have seen forum posts or third-party content that recommend disabling or bypassing Protected View to prevent this issue. We strongly discourage this step as a resolution.

This issue has not occurred with MSI Office installs or with upgrades from Windows 8.1.

Additionally, if your files are blocked but you are getting a Windows Security type of message, check out this blog as a possibility:

    I have a similar problem after updating from Windows 8.1 to Windows 10. My excel files open as read only files and says I need administrative access to change. Well, I am the only person using this PC and I am set up as the administrator. Nothing I have
    tried so far works.

    Unblocking the file in file properties as described in the linked webpage worked for me and I could open the downloaded word file received as an email attachment. Thank you.
