The distributed.net dnetc MSI installer is designed to not only be friendly to new users, but it is also easy for network administrators to rapidly deploy to machines within their Windows domains. When the MSI installer is run interactively it prompts for the participant’s email address. It defaults to “rc5@distributed.net” if it cannot find another address from an existing dnetc.ini file. The default can be changed by editing the MSI Property called “DNETC_PARTICIPANT_ID”. Additionally, the default installation startup mode is normally to create a shortcut in the All Users’ Startup folder. If you want to make the MSI installer default to installing the client as a service, you can change the MSI Property called “DNETC_STARTMODE” and changing it from “AllStartup” to “Service”.
