Applies to: Microsoft Office 2013 Service Pack 1Excel 2013Office Home and Student 2013 RT

This article describes update KB3115455 for Microsoft Excel 2013, which was released on August 9, 2016. This update also applies to Office Home and Student 2013 RT. This update has a prerequisite.

Be aware that the update in the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2013. It doesn't apply to the Office 2013 Click-to-Run editions, such as Microsoft Office 365 Home. (How to determine?)

Improvements and fixes

Fixes the following issues:

  • Assume that you copy and paste a range of cells that has an ID property set in Excel 2013. If you use the ClearContents method to clear the content of the pasted cells, Excel 2013 may crash.
  • Assume that you insert a spreadsheet to a notebook in OneNote 2013. When you select Edit and try to insert a comment in a cell in Excel 2013, Excel 2013 may crash.
  • Excel 2013 silently blocks the loading of untrusted HTML files. This issue occurs after you install MS16-088: Description of the security update for Excel 2013: July 12, 2016 (KB3115262). After you install this new update, Excel 2013 will open HTML documents (even if they're renamed as .xls files) in protected view instead of silently failing.
