What does instal mean?
To instal something is to put it into the correct place and prepare it for use. The word most often describes installing software, an operating system, a printer driver, electrical equipment, or another practical component. It may also refer to formally placing someone in an office: a government can instal a new minister, a court can instal a judge, or an organization can instal an official in a ceremonial role. The verb is neutral in ordinary technical and domestic contexts, while the appointment sense often carries a more formal or institutional tone. In British and Canadian English, both instal and install are widely recognized, although instal is the more characteristic spelling. In American English, install is the conventional form. Although the technical sense is now especially familiar through computers and consumer devices, the word’s older meaning of establishing someone in authority remains in formal and historical usage.

Where does instal come from?
The word entered Middle English through Old French installer, which was derived from Latin installare, meaning “to place in” or “set up in place.” Its prefix in- and the Latin root stāre, meaning “to stand,” also underlie related words such as station, stable, and statute. The later British spelling instal reflects the traditional distinction between verbs ending in -il and those ending in -ill, although modern dictionaries also commonly accept install in British usage.
