How to restart program automatically if it crashes in Windows?

Question

How can I start my program automatically if it crashes on windows 2003 server? Sometimes my program just crashes, is there a way in windows or settings that I can set?

Answer 1

There are several ways to create a process supervisor/guardian process on Windows. First, is to leverage windows command line capabilities. Create a bat file:

@echo off
:start
start /w "your app to watch.exe"
goto start

start /w will wait for the process to exit. When the process crashes and exits, the bat script will relaunch it.

Another option is to use free supervisor tool https://github.com/chebum/Supervisor. It allows to restart the crashed app, plus it allows to monitor two or more apps at once and it will automatically close these apps when supervisor's window is closed.
