On a client machine, open a browser and navigate to the ClickOnce URL.
Click the Install link.
Notes:
The ClickOnce URL follows the format https://<deployment machine>:<port>/p6professionalcloud/en/publishP6.html.
ClickOnce allows you to configure the P6 Professional installation so that the user does not need to configure anything in order to install and run P6 Professional. However, this is only supported for the P6 Pro Cloud Connect driver type. If your users need to connect using a different driver type, they can still download and install from the ClickOnce page, however they will need to configure the connection separately using Database Configuration. See the P6 Professional Administrator's Guide for further information.
