The Web-based endpoint cannot run on a computer where another endpoint is already running. For example, you cannot run the Web-based endpoint on a computer where the endpoint for Microsoft Windows is installed and running. When you attempt to download it, you will receive an error message.
Correspondingly, if the Web-based endpoint is running on a computer, you can install one of the conventional endpoints on that computer. However, the conventional endpoint will not start running automatically once the installation completes. If the Web-based endpoint is running, you must either stop it before installing another endpoint, or else restart the computer after you complete the installation. The new endpoint will then start running automatically because the Web-based endpoint will no longer be present.
