friendlyway composer 7

I downloaded and installed friendlyway composer. Now I’m trying to install player on the same computer but the following error message is being displayed: “friendlyway player 7 may not be installed on machine where friendlyway composer 7 has already been installed”. So can I use composer and player on the same machine or is it impossible? You can use both applications on the same computer, but you don't need to install player separately since it is being installed with composer. That means player is already installed on your machine. And the player setup is to be used on separate computers that are intended for the content playback but not for creating the contents.
