Office Web Apps 2013 KB2592525 not installing

I’ve recently installed Office Web Apps 2013. The installation is straight forward and documented on Technet . However, there was on tricky issue. KB2592525 is a prerequisite and the PS New-OfficeWebAppsFarm cmdlet checks if the KB2592525 is installed. I was installing on a Windows Server 2008 R2 SP1 with all the actual patches. But KB2592525 was not installed and the KB2592525 installer refused to install on this machine. One way to get around this issue is to force the update using pkgmgr.

  1. Download KB2592525 to folder on your system
  2. Create a new folder called “files”
  3. Extract the MSU: expand Windows6.1-KB2592525-x64.msu –F:* .\install
  4. go to files
  5. Install using Pkgmgr: pkgmgr.exe /n:c:\install\Windows6.1-KB2592525-x64.xml

That’s it, and the New-OfficeWebAppsFarm cmdlet will accept this workaround.
