Its been awhile since I used it, I could swear they were separate and isolated installers. If you want this VM to be isolated from the conneciton server I think if you uninstall the vmware agent and when you reinstall make sure the composer and instant clone components are disabled that should prevent it from automatically connecting to the connection server. Without those I think it asks you to register to a connection server, see if you can skip that part if thats the case.
Try this reference as well, I've followed some of his articles with good luck
