In this article, I will walk through all the prerequisites required to be installed before installing the Office Online Server. Just make sure that you have installed the latest update of Windows Server. If for some reason, you can’t install the latest, then make sure that you have at least KB… If you don’t have that level, then some or one of the prerequisites will fail to install and your installation will hang in between.
For convenience, please download all 4 required softwares in advance.
- .NET Framework 4.5.2
- Visual C++ Redistributable Packages for Visual Studio 2013
- Visual C++ Redistributable for Visual Studio 2015
- IdentityModel.Extention.dll
Install the prerequisite
First, we have to enable/configure the Windows feature. Please follow the below steps.
- Login with Service Account (should be local Admin on the Server).
