With the "Install Component" dialog active, select the file with the component's source (?.PAS). Use the Browse button to select the unit, or enter the name of the unit you want to install in the "Unit File Name" edit box.
Note 1: If the unit's folder is in the Search Path, a full path name is not required. If the folder containing the unit file is not in the Search Path, it will be added to the end.
Note 2: The "Search Path" edit box displays the path used by Delphi to search for files. Leave this as it is.
