In my PC Mac/Windows/Linux standalone build settings, it only gives me the option to build on the same OS I have--Linux. How can I build for Windows from Linux? What package do I have to download? --- Update: I realize the option to add build support was when I installed the version of Unity I'm using, but I can't figure out how to add build support for an OS AFTER the version is already installed. To workaround this I am installing the newest version of Unity with all OS build support. To be clear, I would still like to figure out how to add build support to my existing version of Unity. --- Edit: Problem solved! Just navigate to the Installs in Unity Hub and click on the vertical ... and modules and install the modules you need. Cheers.
