This can update your app
You are going to want to make your program download this program. Then create a text file named 'Update.txt' and the first line should be the link to the download, it should be a zip file. And the next lines are the file/directory names (just the file/directory name, not the path). And then run the exe 'AppUpdater.exe'. The updater will leave a text file, if it says Successful, then that means that everything worked, and if it says Failed, then that means something went wrong. If you want to automatically start the program then create a text file named 'Startup.txt' and put in the executable name in (name not path).
