How to find the version or build number for an Office Web Apps 2013 Farm

  • 發行項

There are multiple ways to find the OWA 2013 patch or build level:

Use PowerShell

  • Check the X-OfficeVersion header value, on an Office Web Apps (OWA) or SharePoint server, replace the highlighted owa01 in red with your owa server url and run

(Invoke-WebRequesthttps://owa01/op/servicebusy.htm).Headers

  • On Office Web Apps server

Get-Content "C:\ProgramData\Microsoft\OfficeWebApps\Data\local\OfficeVersion.inc"

On an Office Web Apps Server, check the OfficeVersion.inc file located here

C:\ProgramData\Microsoft\OfficeWebApps\Data\local\OfficeVersion.inc

 You can also check the X-OfficeVersion header value right from the browser. Please head over to my colleague Tom's blog post here.

    Hi Sammy,The script does not work if you installed WCA and then patched it! i have run this on 2 of my WCA farms with the March 2013 CU and it is showing the RTM version 15.0.4420.1017It may work for slipstreamed installs but it doesn't give you the WCA patched version for upgraded WCA servers/farms.

    Agree with coolhand - installing SP does not change reported version

    @ AD-SPbb, if you do a reverse internet search on the build number, you should be able to determine the CU or service pack level, for example my build number is 15.0.4481.1508 which is OWA April 2013 CU.

    Thanks,
    Sammy

    Thank you all for your feedback, I have updated this post with more reliable ways to find the current WAC build number. Thanks to Tom S. and Joe Rodgers for their input.

    not sure this works the way you are expecting.  on several upgraded farms, I've checked this registry key and it is still set at the RTM version.  so far the only reliable method I have been able to use is to look up the kb listed in "programs and featuresview installed updates"
