History

PowerPoint 2010 and 2013 for Windows originally included support for embedding YouTube videos that were in an old format that YouTube no longer supports.  As this old format started disappearing from the YouTube service, the support for YouTube videos in PowerPoint started faltering. These changes led us to disable support for inserting online videos from the product because we could not reliably support playing back YouTube videos.

What the update brings

Since the time playback of online videos was disabled in PowerPoint, the PowerPoint team has been hard at work to re-enable support for YouTube in a way that is resilient to changes and more robust. For PowerPoint 2013 we now use a browser to host these videos, which provides us the resiliency. This not only means that we can support HTML5 videos but also that we will be able to playback YouTube videos as long as they can playback in any browser. Both PowerPoint 2010 and 2013 for Windows are updated to include support for YouTube videos in the newer HTML5 and Shockwave Flash ActionScript 3.0 formats.

 Note: The insert online video option is limited to YouTube support for both PowerPoint 2010 and 2013.

If you try to edit an Office file (Word, PowerPoint or Excel) from a SharePoint 2010 Document Library while using an iPad with MS Office applications installed, the file will not open and there is an error “there is no SharePoint Foundation application available to open
the app.”

SharePoint 2010 requires a plugin or active X to launch client applications, and neither of those are allowed on the iOS platform. SharePoint 2013 and SharePoint Online support protocol handlers that work with iPad.

To work around this behavior:

Option 1 – Add a Place within the application that will connect to the SharePoint Document Library.

1. To do this open any of the installed Microsoft Office applications
   (Word, Excel or PowerPoint).
2. On the opening window choose Add a Place.
3. In the Add a Place window click on SharePoint Site URL
4. In the SharePoint URL window enter the url or internet address of the SharePoint Document Library.
5. Click Next - when prompted enter the username and password.

Option 2 – download a copy of the file

1. When in the Document Library click on Download a copy.
2. The document will be displayed in the browser window with the option to choose how to open in the appropriate application.
3. When the file opens it will be read only with the option to edit and save.

 UPDATE:

Upon further analysis of the files that have been submitted to us for investigation, the analysts have determined that the files are encrypted with a private and public key. Unless the private key is available, the files will not be able to be recovered. The private key is more than likely held by the attacker.The premise of ransom ware such as this is that if a person pays the ransom, a key is provided to unlock the files. The best course of action is to clean up the malware and then restore files from a backup.

More Information:

We are currently investigating an ongoing situation where users may encounter an error when trying to open Office documents.

The error can happen opening any Office file type, not just Excel files as shown in the image below. The error says:

"Cannot open the file ... because the file format or extension is not valid. Verify, that the file has not been corrupted and that the file extension matches the format of the file."

With PowerPoint binary files (.PPT) , you will see a dialog similar to the following screenshot. We don't have OOXML samples yet but will post images once we have these.

PowerPoint

• The Visual Basic, and Macros options are disabled/greyed on the ribbon.
• When opening presentations with VBA code, the user receives the following message:
  "The document contains macros. Macro language support for this application is disabled. Features requiring VBA are not available. Would you like to open this document read-only?"

Word

• The Macro button is not greyed out but when trying to run or record a macro they receive the following
  message, “The function you are attempting to run contains macros or content that requires macro language support"

Access:

• When running wizards the receive the following error,  “This feature isn't installed, or has been disabled"
• When opening VBA editor the user receives “"Microsoft Access is unable to load the Visual Basic for
  Applications dynamic-link library (dll) Vbe7" when opening the Visual Basic Editor (VBE)”

Excel

• The Visual Basic, Macros and Record Macro options are disabled/greyed on the ribbon.
• When opening workbooks with VBA code, the user receive the following message, “The Visual Basic for
  Applications (VBA) macros in this workbook are corrupted and have been deleted."

In most cases repairing MS Office fixes the issue. 

What we believe is happening is there is a registry cleaner or system maintenance type application removing some our registry keys that we
need for VBA to run successfully.  In the above scenarios when the MS Office application was installed the VBA worked properly.

This problem can happen when the DisplayLinkManager driver is installed on the system. This problem is known to happen with DisplayLinkDriver versions 5.5.29055.0 or 5.6.30272.0.

To resolve this problem, update the DisplayLink driver. To do this, connect to http://www.displaylink.com/support/downloads.php and install any version of the DisplayLinkDriver later than 5.6.30272.0.

Note: The other Office Applications (Access, Word, Excel, Outlook) will also crash if using the old DisplayLink Driver.

If you suspect you are running into this error, you should be able to resolve the problem by deleting all files in the following path:

%LOCALAPPDATA%\Microsoft\DRM

also, make sure to rename or delete the following registry key (if you choose to delete the key, be sure to back it up first)::
