# Automatic start-up at boot
You can make Wallpaper Engine launch when your computer starts by going to the Wallpaper Engine settings and navigating to the "General" tab. At the top, you can enable the automatic startup option which will launch the application quietly in the background whenever your system boots up.
# What is the difference between "high-priority" and the "normal" start-up option?
When you select the high-priority option, Wallpaper Engine will register a Windows service. This means that Wallpaper Engine will start before other programs you have configured to automatically start alongside Windows. It will not affect the performance of the application in any other way.
The downside to using this high-priority option is that it can be less reliable, mainly due to the fact that some antivirus will overreact and block Wallpaper Engine from starting in this mode because they misidentify this as malicious behavior.
# I have enabled the automatic startup but it is not working, what can I do?
If you are using the high-priority option, try to switch to normal automatic start-up by disabling the high-priority option. As explained above, high-priority mode starts quicker but is less reliable for various reasons, mainly because it is sometimes blocked by antivirus software.
If you are using normal-priority option and the app is not launching alongside Windows, try changing the option to high-priority and see if the problem goes away.
If neither the high-priority or normal-priority option work for you, check the antivirus software you have installed on your system. Some antivirus and firewall applications sometimes block Wallpaper Engine from automatically starting when your computer boots up. Your antivirus software likely has a "whitelist" feature which allows you to ignore certain folders or applications, make sure to whitelist the wallpaper_engine install directory and all executables in it.
Another rare cause can be that if you (or an application on your system) set the Wallpaper Engine .exe files to be run as admin only then it cannot automatically start either, you will need to remove the admin setting and toggle the automatic startup off and back on.
If the automatic startup does not work, the answer virtually always is somehow related to overzealous antivirus software. If you have antivirus or firewall applications installed, please double-check all their settings and security levels.
