Nox Reloaded has all the stuff you need including Westwood Online.

In case of persistent difficulties you can try NoxSolution.

Can anyone help direct me to how to install Westwood Online or the alternative version to play Sunday night games? I have Nox Reloaded and Nox on GOG Galaxy, but information from Google is kind of scarce on installing the online components to play with people.

Any help would be appreciated. I'm sure there is some thread here that already covers this so I'll keep looking. If you could post the link it would be great!
