Hi All I heard that its recommended to install kepware and then restart pc before installing ignition. I was told that it is to do with the opc components and how they are installed - kepware has some components like name server which ignition does not have and there is potential that if ignition was installed first then kepware might skip some components and detect them as already installed I wonder if anybody on the forum heard about this?

Shouldn't matter. OPC Core Components are only necessary for OPC Classic/DA connections. You probably don't need them, Kepware supports OPC UA. ---
