OPC Client DA/UA Class not registered

I have recently re-installed Factory IO version v2.5.1 on Windows 10 x64

I was going to look at UPC-UA but it threw an error.
Retrieving the COM class factory for component with CLSID {} failed due to the following error: 80040154 Class not registered.

I can’t recall if I am supposed to install and additional component.


I suspect this error occurs when FIO is trying to browse for OPC DA servers.
Error code 0x80040154 indicates that a DCOM component is not properly registered on Windows.
Do you have an OPC DA server installed on your computer?
