subprocess.call and ending current program

Question

My main program checks if a new version of itself is available and if so it downloads the new installer file and runs it: subprocess.call(["installer.exe"], shell=True) But in order to overwrite the old files, it needs to exit itself after calling the subprocess. How can I achieve this?

Answer 1

In Windows, just start your installer program instead of waiting for it.

import subprocess

subprocess.call(["start","installer.exe"],shell=True)
print("out")

Running this will print out immediately and returns to the console if this is the last statement (or call sys.exit())
