buildWebPlayer not working

Hello, i’m done the build from command line, but not working.

This is my line, executed from CMD in windows.

Thanks for the help.

Sorry my bad english.

"C:\Program Files\Unity\Editor\Unity.exe" -quit -batchmode -buildWebPlayer "C:\Users\erika\Desktop\Actividades\Actividades\New Unity Project\Builds\build"

The Webplayer is no longer a supported platform. Try WebGL/Html5.
