installer
in-STAW-ler
/ɪnˈstɔːlər/

An installer is the guide. It unpacks compressed files, places them in the correct folders, creates shortcuts, and ensures the operating system knows the program is there.
The story behind the word. The root 'install' originally referred to placing a priest or official into a physical 'stall' or seat of office during a formal ceremony. In the 20th century, it was adapted to mean putting a piece of machinery or software into its proper place so it could perform its duties.
