Welcome to the CircleDock forum here at Donationcoder.com
If I am understanding correctly you wish to have CircleDock start on boot, or when your system starts?
That being the case there are a number of solutions.
In Windows XP.
Create a shortcut of the CircleDock.exe and then place that Shortcut in to the Startup file in your start menu
In Windows Vista and 7 in gets a little more complicated.
If you have Windows Vista or 7, let me know, and I will get you some details on the installation.
Unfortunately I am short on time at the moment.
If what you are requesting is something else, let me know, I am here to help
