Let me give you a brief about what Office Web App Server is for those who don’t know what it is used for. Its basically a server which provides the Office Services to edit or view the office documents in the browser itself without the need of office installed on local machine of end users.
Installing OWA Server on Windows Server is not a pain until its Windows Server 2012 R2. Normally one would think like SharePoint it would give the list of pre-requisites which would be installed automatically but it doesn’t do that.
So, if you try to install Office Web App Server 2013 on Windows 2012 R2, you would face a mysterious error stating that it requires .Net Framework version 4.0 or greater and IIS version 7.0 or later which I already had in my windows server.
So, here are the following steps which you can follow and install the Office Web App Server 2013 on Windows Server 2012 R2.
- Install .Net Framework v 4.5.2 (Yes it is required in case of Win 2012 R2)
- Run the following command on the powershell
- Restart the server.
- Now, install the Office Web App Server 2013
- After that install Office Web App Server 2013 SP1 (This is also mandatory for Win 2012 R2)
Although all steps are listed in Technet, but still I also missed these steps. For other servers and steps to follow on those servers follow the technet url.
