I had been trying like crazy to find the “windows target support” download for 2018, but no success…
Is windows build support removed from mac?
I had projects that I open back and forth from mac and windows machine, and I can’t switch build target all the time…
I think the problem is that when you use IL2CPP you can only build macOS on macOS and Windows on Windows. Switch back to Mono and it should be available, as long as you installed the Mono build package for the foreign platform in question.
I reinstalled Unity with the same settings, and for some reason now works !! Thank you for your suggestion.
