Lync 2013 Office Web Apps (WAC) not working on Windows 8.1 stations

Standard

*** UPDATE ***

This issue has been resolved in the WAC November 2013 update: http://support.microsoft.com/kb/2837634/en-us.

Remember that in order to install this update you must first remove the existing farm, install the update and then recreate the farm. See this article if you need a reminder.

Original post:

Did some maintenance last weekend, installing the October 2013 update and other updates.
additionally, Had my work station upgraded to Windows 8.1.

The first thing I noticed was that PowerPoint presentations content is unavailable after installing the updates, with the following error:
“Sorry, we ran into a problem displaying the presentation. Please try again.”

Error Messgae

After testing this on multiple machines with multiple accounts, I can verify that Lync 2013 clients on Windows 8.1, are unable to present or view PowerPoint content on Office Web Apps Server.

This goes for Office Web Apps Servers installed on Windows Server 2008R2, Windows Server 2012 and Windows Server 2012R2, both internally and externally.

Lync 2013 clients on any Operating system OTHER than Windows 8.1 are not affected and can use the Office Web Apps services with no issues.

Keep that in mind before upgrading to Windows 8.1!

    • Hi Marcel,
      A system issue for sure, as I have been receiving the same complaints from other colleagues as well.
      Since Office 365 is a Microsoft Lync Server version that is not available to the public, I can only assume they patched something there…
      Hopefully we’ll get a fix soon – Thanks for the update!

    • That’s not an option if you need to manage a call with 10 participants – would be easier to use a Windows 8 device…
      But for the occasional meeting this is a great work around!

  1. I can confirm that this has officially been fixed by Microsoft. I’m running Windows 8.1 on my laptop with IE11. My Lync lab is Lync 2013 on Server 2012. My Office Web Apps is Server 2012. There was a patch released 12th November for Office Web Apps that definitely fixes it.
    http://support.microsoft.com/kb/2837634/en-us

    Download the patch and save it. Then follow this procedure for applying updates to Office Web Apps server http://technet.microsoft.com/en-us/library/jj966220.aspx.

    In my case I have a single server so it is as follows:
    1. Open powershell as administrator and run get-officewebappsfarm and make a note of the parameters -InternalUrl, -ExternalUrl and -CertificateName.
    2. Now run Remove-OfficeWebAppsMachine
    3. Install the update
    4. Restart when prompted
    5. log on after the restart
    6. Run powershell as administrator and add your Office Web Apps Farm again using the parameters you copied from step 1
    eg;- New-OfficeWebAppsFarm -InternalUrl “https://internalFQDN/” -ExternalUrl “https://externalFQDN.domain.com/” -CertificateName “OfficeWebAppsCertificate” -EditingEnabled
    7. You will see “Setting EditingEnabled to TRUE. You should only do this if users of this Office Web Apps Server have licenses that permit editing using Office Web Apps. Continue with this operation?”
    [Y] Yes [N] No [S] Suspend [?] Help (default is “Y”): Y
    8. Test using your internal URL eg; https://internalFQDN/hosting/discovery and make sure you get no errors in the output.
    9. Log out of Lync and then back in. Meet Now and upload a PowerPoint presentation. It should load. I also copied the meeting entry info and pasted into Chrome with ?SL=1 at the end and entered as a guest to see if I could see the presentation. And I could.

    I think it is actually a bit quicker to upload and display the presentation than it was before, but that could just be wishful thinking.

    Hope this helps.
