SharePoint Server 2016 error Microsoft Office Online Server 2016 cant be installed on the same machine as a Microsoft SharePoint Server product


If you try to install Office Online Server 2016 Preview on a server where SharePoint Server 2016 IT Preview is already installed, you receive below error -

Microsoft Office Online Server 2016 can't be installed on the same machine as a Microsoft SharePoint Server product.

Resolution

Install Microsoft Office Online Server 2016 on a separate server. Yes, you read it correctly, it requires a separate server and cannot be installed on the same server where SharePoint 2016 is installed. This is similar to how Office Web Apps work, it requires a dedicated server.

Additionally, now Excel Services is also not a part of SharePoint 2016 directly. You will need Excel Online on Office Online Server 2016 for this.

There is going to be a pain setting up a development environment for SharePoint 2016. You would need to invest more for the Development Environment and get an additional box to use a few SharePoint 2016 features.
